What is in expanded form?

$8\times10+7\times1+5\times\left(\frac{1}{10}\right)+3\times\left(\frac{1}{100}\right)$

$8\times10+7\times10+5\times\left(\frac{1}{10}\right)+3\times\left(\frac{1}{100}\right)$

$8\times100+7\times1+5\times\left(\frac{1}{100}\right)+3\times\left(\frac{1}{100}\right)$

$8\times10+7\times1+5\times\left(\frac{1}{10}\right)+3\times\left(\frac{1}{10}\right)$

$8\times100+7\times1+5\times\left(\frac{1}{10}\right)+3\times\left(\frac{1}{1000}\right)$

Explanation

When we write a number in expanded form, we multiply each digit by its place value.

is in the tens place, so we multiply by .

$8\times10=80$

is in the ones place, so we multiply by .

$7\times1=7$

is in the tenths place, so we multiply by $\frac{1}{10}$ .

$5\times\frac{1}{10}=.5$

is in the hundredths place, so we multiply by $\frac{1}{100}$ .

$3\times\frac{1}{100}=.03$

Then we add the products together.

$\frac{\begin{array}[b]{r}80.00\7.00\ +\ .50\ .03 \end{array}}{ \ \ \space87.53}$

What is in expanded form?

$1\times10+2\times1+8\times\left(\frac{1}{10}\right)+4\times\left(\frac{1}{100}\right)$

$1\times10+2\times10+8\times\left(\frac{1}{10}\right)+4\times\left(\frac{1}{100}\right)$

$1\times10+2\times1+8\times\left(\frac{1}{10}\right)+4\times\left(\frac{1}{1000}\right)$

$1\times10+2\times1+8\times\left(\frac{1}{100}\right)+4\times\left(\frac{1}{100}\right)$

$1\times10+2\times10+8\times\left(\frac{1}{100}\right)+4\times\left(\frac{1}{100}\right)$

Explanation

When we write a number in expanded form, we multiply each digit by its place value.

is in the tens place, so we multiply by .

$1\times10=10$

is in the ones place, so we multiply by .

$2\times1=2$

is in the tenths place, so we multiply by $\frac{1}{10}$ .

$8\times\frac{1}{10}=.8$

is in the hundredths place, so we multiply by $\frac{1}{100}$ .

$4\times\frac{1}{100}=.04$

Then we add the products together.

$\frac{\begin{array}[b]{r}10.00\2.00\ +\ .80\ .04 \end{array}}{ \ \ \space12.84}$

What is in expanded form?

$5\times10+3\times1+2\times\left(\frac{1}{10}\right)+6\times\left(\frac{1}{100}\right)$

$5\times10+3\times1+2\times\left(\frac{1}{10}\right)+6\times\left(\frac{1}{1000}\right)$

$5\times10+3\times1+2\times\left(\frac{1}{100}\right)+6\times\left(\frac{1}{1000}\right)$

$5\times10+3\times100+2\times\left(\frac{1}{10}\right)+6\times\left(\frac{1}{100}\right)$

$5\times10+3\times100+2\times\left(\frac{1}{10}\right)+6\times\left(\frac{1}{1000}\right)$

Explanation

When we write a number in expanded form, we multiply each digit by its place value.

is in the tens place, so we multiply by .

$5\times10=50$

is in the ones place, so we multiply by .

$3\times1=3$

is in the tenths place, so we multiply by $\frac{1}{10}$ .

$2\times\frac{1}{10}=.2$

is in the hundredths place, so we multiply by $\frac{1}{100}$ .

$6\times\frac{1}{100}=.06$

Then we add the products together.

$\frac{\begin{array}[b]{r}50.00\3.00\ +\ .20\ .06 \end{array}}{ \ \ \space53.26}$
