Adding Multi-Digit Decimals - 6th Grade Math

Card 0 of 308

Question

Find the sum of 2.4, 55, and 6.21.

Answer

To find the sum, you need to add. Line up all numbers vertically. Since one number has a decimal to the tenths place, one has a decimal to the hundredths place, and one has no decimal, be extra careful to line up the digits correctly! To help you, add a zero to the end of 2.4, and add two zeroes to the end of 55 so that all the digits line up correctly.

$\begin{matrix} &\ 2.40 \ & 55.00\ + & \ 6.21 \end{matrix}$

Now, add down each column, starting on the right side and moving to the left.

The sum is 63.61.

Question

Samantha went to the toy store and bought three things:

2 bouncy balls: $0.49 each

1 coloring book: $4.75 each

Question

Above is the menu at the concession stand at a school carnival. Ken wants to purchase a hamburger, a medium order of fries, and medium soda for himself, and a hot dog, a small order of fries, and a small soda for his friend Donna. He hands the clerk a $10 bill and a $5 bill. He has some $1 bills in his pocket; how many of them will he need to hand to the clerk along with the other two bills?

(No tax is charged, since this is a school event)

Answer

The items Ken purchases are as follows:

Hamburger: $4.89

Medium fries: $2.79

Medium soda: $1.69

Hot dog: $4.39

Small fries: $2.29

Small soda: $1.09

The sum of the prices of these items:

$\underline{1.09}$

Subtract from $20:

Rounding this up - Ken needs to give the clerk three more $1 bills.

Answer

When we add with multi-digit numbers with decimals, we start with the numbers furthest to the right and work our way towards the left.

Add the numbers in the hundredths place:

Your work should look something like this:

$\begin{array}{r}\overset{\ ~}{ 4 } \overset{\ ~}{ 6 .}\overset{\ ~ }{ 3 } 4 \ + \overset{\ ~ }{ 4 }\overset{\ ~ }{ 6 .}\overset{ }{ 3 } \overset{~\ }{ 3 } \ \hline \space{} , \space{, } \space{, } 7 \end{array}$

Add the numbers in the tenths place:

Your work should look something like this:

*Notice that the decimal moves directly down when we are adding decimal numbers.

$\begin{array}{r}\overset{\ ~}{ 4 } \overset{\ ~ }{ 6 .}\overset{\ ~ }{ 3 } 4 \ + \overset{\ ~ }{ 4 }\overset{\ ~ }{ 6 .}\overset{ }{ 3 } \overset{~\ }{ 3 } \ \hline \space{} , \space{,. } 6 \space{, } 7 \end{array}$

Add the numbers in the ones place:

Because this sum is greater than 9, we write the 2 from the ones place and carry the 1 from the tens place over to the left. Your work should look something like this:

$\begin{array}{r}\overset{\ 1 }{ 4 } \overset{\ ~ }{ 6 .}\overset{\ ~ }{ 3 } 4 \ + \overset{\ ~ }{ 4 }\overset{\ ~ }{ 6 .}\overset{ }{ 3 } \overset{~\ }{ 3 } \ \hline \space{} , 2 \space{,. } 6 \space{, } 7 \end{array}$

Add the numbers in the tens place including the one carried over:

Your final answer should be:

$\begin{array}{r}\overset{\ 1 }{ 4 } \overset{\ ~ }{ 6 .}\overset{\ ~ }{ 3 } 4 \ + \overset{\ ~ }{ 4 }\overset{\ ~ }{ 6 .}\overset{ }{ 3 } \overset{~\ }{ 3 } \ \hline 9 \space{} , 2 \space{,. } 6 \space{, } 7 \end{array}$

$\begin{array}{r}\overset{\ ~ }{ 1 } \overset{\ 1 }{ 1 .}\overset{\ ~ }{ 7 } 0 \ + \overset{\ ~ }{ 1 }\overset{\ ~ }{ 1 .}\overset{ }{ 4 } \overset{~\ }{ 8 } \ \hline \space{} , 3 \space{,. } 1 \space{, } 8 \end{array}$

Add the numbers in the tens place:

Your final answer should be:

$\begin{array}{r}\overset{\ ~ }{ 1 } \overset{\ 1 }{ 1 .}\overset{\ ~ }{ 7 } 0 \ + \overset{\ ~ }{ 1 }\overset{\ ~ }{ 1 .}\overset{ }{ 4 } \overset{~\ }{ 8 } \ \hline 2 \space{} , 3 \space{,. } 1 \space{, } 8 \end{array}$

Question

Solve:

$\begin{array}{r}\overset{\ ~}{1} \overset{\ ~}{7.}\overset{\ ~}{5}6\ + \overset{\ ~ }{4}\overset{\ ~ }{4.}\overset{ }{6} \overset{~\ }{2} \ \hline \end{array}$

Answer

When we add with multi-digit numbers with decimals, we start with the numbers furthest to the right and work our way towards the left.

Add the numbers in the hundredths place:

Your work should look something like this:

$\begin{array}{r}\overset{\ ~}{1} \overset{\ ~}{7.}\overset{\ ~}{5}6\ + \overset{\ ~ }{4}\overset{\ ~ }{4.}\overset{ }{6} \overset{~\ }{2} \ \hline \space{} , \space{, } \space{, }8\end{array}$

Add the numbers in the tenths place:

Because this sum is greater than 9, we write the 1 from the ones place and carry the 1 from the tens place over to the left. Your work should look something like this:

Your work should look something like this:

$\begin{array}{r}\overset{\ ~}{1} \overset{\ 1}{7.}\overset{\ ~}{5}6\ + \overset{\ ~ }{4}\overset{\ ~ }{4.}\overset{ }{6} \overset{~\ }{2} \ \hline \space{} , \space{,. }1\space{, }8\end{array}$

Add the numbers in the ones place:

Because this sum is greater than 9, we write the 2 from the ones place and carry the 1 from the tens place over to the left. Your work should look something like this:

$\begin{array}{r}\overset{\ 1}{1} \overset{\ 1}{7.}\overset{\ ~}{5}6\ + \overset{\ ~ }{4}\overset{\ ~ }{4.}\overset{ }{6} \overset{~\ }{2} \ \hline \space{} , 2\space{,. }1\space{, }8\end{array}$

Your final answer should be: 62.18

$\begin{array}{r}\overset{\ 1}{1} \overset{\ 1}{7.}\overset{\ ~}{5}6\ + \overset{\ ~ }{4}\overset{\ ~ }{4.}\overset{ }{6} \overset{~\ }{2} \ \hline 6\space{} , 2\space{,. }1\space{, }8\end{array}$

Question

Solve:

$\begin{array}{r}\overset{\ ~}{1} \overset{\ ~}{3.}\overset{\ ~}{7}4\ + \overset{\ ~ }{2}\overset{\ ~ }{6.}\overset{ }{6} \overset{~\ }{5} \ \hline \end{array}$

Answer

When we add with multi-digit numbers with decimals, we start with the numbers furthest to the right and work our way towards the left.

Add the numbers in the hundredths place:

Your work should look something like this:

$\begin{array}{r}\overset{\ ~}{1} \overset{\ ~}{3.}\overset{\ ~}{7}4\ + \overset{\ ~ }{2}\overset{\ ~ }{6.}\overset{ }{6} \overset{~\ }{5} \ \hline \space{} , \space{, } \space{, }9\end{array}$

Add the numbers in the tenths place:

Because this sum is greater than 9, we write the 3 from the ones place and carry the 1 from the tens place over to the left. Your work should look something like this:

Your work should look something like this:

$\begin{array}{r}\overset{\ ~}{1} \overset{\ 1}{3.}\overset{\ ~}{7}4\ + \overset{\ ~ }{2}\overset{\ ~ }{6.}\overset{ }{6} \overset{~\ }{5} \ \hline \space{} , \space{,. }3\space{, }9\end{array}$

Add the numbers in the ones place:

Because this sum is greater than 9, we write the 0 from the ones place and carry the 1 from the tens place over to the left. Your work should look something like this:

$\begin{array}{r}\overset{\ 1}{1} \overset{\ 1}{3.}\overset{\ ~}{7}4\ + \overset{\ ~ }{2}\overset{\ ~ }{6.}\overset{ }{6} \overset{~\ }{5} \ \hline \space{} , 0\space{,. }3\space{, }9\end{array}$

Your final answer should be: 40.39

$\begin{array}{r}\overset{\ 1}{1} \overset{\ 1}{3.}\overset{\ ~}{7}4\ + \overset{\ ~ }{2}\overset{\ ~ }{6.}\overset{ }{6} \overset{~\ }{5} \ \hline 4\space{} , 0\space{,. }3\space{, }9\end{array}$

Question

Solve:

$\begin{array}{r}\overset{\ ~}{1} \overset{\ ~}{5.}\overset{\ ~}{2}7\ + \overset{\ ~ }{4}\overset{\ ~ }{0.}\overset{ }{4} \overset{~\ }{8} \ \hline \end{array}$

Answer

When we add with multi-digit numbers with decimals, we start with the numbers furthest to the right and work our way towards the left.

Add the numbers in the hundredths place:

Because this sum is greater than 9, we write the 5 from the ones place and carry the 1 from the tens place over to the left. Your work should look something like this:

$\begin{array}{r}\overset{\ ~}{1} \overset{\ ~}{5.}\overset{\ 1}{2}7\ + \overset{\ ~ }{4}\overset{\ ~ }{0.}\overset{ }{4} \overset{~\ }{8} \ \hline \space{} , \space{, } \space{, }5\end{array}$

Add the numbers in the tenths place:

Your work should look something like this:

*Notice that the decimal moves directly down when we are adding decimal numbers.

$\begin{array}{r}\overset{\ ~}{1} \overset{\ ~}{5.}\overset{\ 1}{2}7\ + \overset{\ ~ }{4}\overset{\ ~ }{0.}\overset{ }{4} \overset{~\ }{8} \ \hline \space{} , \space{,. }7\space{, }5\end{array}$

Add the numbers in the ones place:

Your work should look something like this:

$\begin{array}{r}\overset{\ ~}{1} \overset{\ ~}{5.}\overset{\ 1}{2}7\ + \overset{\ ~ }{4}\overset{\ ~ }{0.}\overset{ }{4} \overset{~\ }{8} \ \hline \space{} , 5\space{,. }7\space{, }5\end{array}$

Your final answer should be: 55.75

$\begin{array}{r}\overset{\ ~}{1} \overset{\ ~}{5.}\overset{\ 1}{2}7\ + \overset{\ ~ }{4}\overset{\ ~ }{0.}\overset{ }{4} \overset{~\ }{8} \ \hline 5\space{} , 5\space{,. }7\space{, }5\end{array}$
