Example Question #155 : Ratio And Proportion

How many \(\displaystyle yards\) are in \(\displaystyle 180\ inches?\)

Possible Answers:

\(\displaystyle 6\)

\(\displaystyle 7\)

\(\displaystyle 4\)

\(\displaystyle 3\)

\(\displaystyle 5\)

Correct answer:

\(\displaystyle 5\)

Explanation:

To solve this problem we can make proportions.

We know that \(\displaystyle 1\ yard=36\ inches\), and we can use \(\displaystyle x\) as our unknown. 

\(\displaystyle \frac{1\ yard}{36\ inches}=\frac{x\ yards}{180\ inches}\)

Next, we want to cross multiply and divide to isolate the \(\displaystyle x\) on one side. 

\(\displaystyle 36\ inches\times x\ yards= 1\ yard \times 180\ inches\)

\(\displaystyle 5\ yards= \frac{1\ yard \times 180\ inches}{36\ inches}\)

The \(\displaystyle \yards\)\(\displaystyle \ inches\) will cancel and we are left with \(\displaystyle 5\ yards\)

Example Question #156 : Ratio And Proportion

How many \(\displaystyle feet\) are in \(\displaystyle 108\ inches?\)

Possible Answers:

\(\displaystyle 10\)

\(\displaystyle 11\)

\(\displaystyle 12\)

\(\displaystyle 9\)

\(\displaystyle 8\)

Correct answer:

\(\displaystyle 9\)

Explanation:

To solve this problem we can make proportions.

We know that \(\displaystyle 1\ foot=12\ inches\), and we can use \(\displaystyle x\) as our unknown. 

\(\displaystyle \frac{1\ foot}{12\ inches}=\frac{x\ feet}{108\ inches}\)

Next, we want to cross multiply and divide to isolate the \(\displaystyle x\) on one side. 

\(\displaystyle 12\ inches\times x\ feet= 1\ foot \times 108\ inches\)

\(\displaystyle 9\ feet= \frac{1\ foot \times 108\ inches}{12\ inches}\)

The \(\displaystyle \yards\)\(\displaystyle \ inches\) will cancel and we are left with \(\displaystyle 9\ feet\)

Example Question #1514 : Common Core Math: Grade 5

Possible Answers:

\(\displaystyle 252\)

\(\displaystyle 240\)

\(\displaystyle 255\)

\(\displaystyle 242\)

\(\displaystyle 290\)

Correct answer:

\(\displaystyle 252\)

Explanation:

To solve this problem we can make proportions.

We know that \(\displaystyle 1\ yard=36\ inches\), and we can use \(\displaystyle x\) as our unknown. 

\(\displaystyle \frac{1\ yard}{36\ inches}=\frac{7\ yards}{x\ inches}\)

Next, we want to cross multiply and divide to isolate the \(\displaystyle x\) on one side. 

\(\displaystyle 36\ inches\times 7\ yards= 1\ yard \times x\ inches\)

\(\displaystyle \frac{36\ inches\times 7\ yards}{1\ yard}= 252\ inches\)

The \(\displaystyle \yards\)\(\displaystyle \ yards\) will cancel and we are left with \(\displaystyle 252\ inches\)

Example Question #821 : Ssat Middle Level Quantitative (Math)

How many \(\displaystyle inches\) are in \(\displaystyle 2\ yards?\)

Possible Answers:

\(\displaystyle 87\)

\(\displaystyle 78\)

\(\displaystyle 68\)

\(\displaystyle 92\)

\(\displaystyle 72\)

Correct answer:

\(\displaystyle 72\)

Explanation:

To solve this problem we can make proportions.

We know that \(\displaystyle 1\ yard=36\ inches\), and we can use \(\displaystyle x\) as our unknown. 

\(\displaystyle \frac{1\ yard}{36\ inches}=\frac{2\ yards}{x\ inches}\)

Next, we want to cross multiply and divide to isolate the \(\displaystyle x\) on one side. 

\(\displaystyle 36\ inches\times 2\ yards= 1\ yard \times x\ inches\)

\(\displaystyle \frac{36\ inches\times 2\ yards}{1\ yard}= 72\ inches\)

The \(\displaystyle \yards\)\(\displaystyle \ yards\) will cancel and we are left with \(\displaystyle 72\ inches\)

Example Question #11 : Measurement & Data

How many \(\displaystyle yards\) are in \(\displaystyle 144\ inches?\)

Possible Answers:

\(\displaystyle 8\)

\(\displaystyle 4\)

\(\displaystyle 6\)

\(\displaystyle 7\)

\(\displaystyle 5\)

Correct answer:

\(\displaystyle 4\)

Explanation:

To solve this problem we can make proportions.

We know that \(\displaystyle 1\ yard=36\ inches\), and we can use \(\displaystyle x\) as our unknown. 

\(\displaystyle \frac{1\ yard}{36\ inches}=\frac{x\ yards}{144\ inches}\)

Next, we want to cross multiply and divide to isolate the \(\displaystyle x\) on one side. 

\(\displaystyle 36\ inches\times x\ yards= 1\ yard \times 144\ inches\)

\(\displaystyle 4\ yards= \frac{1\ yard \times 144\ inches}{36\ inches}\)

The \(\displaystyle \yards\)\(\displaystyle \ inches\) will cancel and we are left with \(\displaystyle 4\ yards\)

To solve this problem we can make proportions.

We know that \(\displaystyle 1\ foot=12\ inches\), and we can use \(\displaystyle x\) as our unknown. 

\(\displaystyle \frac{1\ foot}{12\ inches}=\frac{x\ feet}{168\ inches}\)

Next, we want to cross multiply and divide to isolate the \(\displaystyle x\) on one side. 

\(\displaystyle 12\ inches\times x\ feet= 1\ foot \times 168\ inches\)

\(\displaystyle 14\ feet= \frac{1\ foot \times 168\ inches}{12\ inches}\)

The \(\displaystyle \yards\)\(\displaystyle \ inches\) will cancel and we are left with \(\displaystyle 14\ feet\)

To solve this problem we can make proportions.

We know that \(\displaystyle 1\ foot=12\ inches\), and we can use \(\displaystyle x\) as our unknown. 

\(\displaystyle \frac{1\ foot}{12\ inches}=\frac{16\ feet}{x\ inches}\)

Next, we want to cross multiply and divide to isolate the \(\displaystyle x\) on one side. 

\(\displaystyle 12\ inches\times 16\ feet= 1\ foot \times x\ inches\)

\(\displaystyle \frac{12\ inches\times 16\ feet}{1\ foot}= 192\ inches\)
