Example Question #6 : Map 5th Grade Math

How many \displaystyle feet are in \displaystyle 72\ inches?

Possible Answers:

\displaystyle 8

\displaystyle 5

\displaystyle 6

\displaystyle 7

Correct answer:

\displaystyle 6

Explanation:

To solve this problem we can make proportions.

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

\displaystyle \frac{1\ foot}{12\ inches}=\frac{x\ feet}{72\ 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 72\ inches

\displaystyle 6\ feet= \frac{1\ foot \times 72\ inches}{12\ inches}

The \displaystyle \yards\displaystyle \ inches will cancel and we are left with \displaystyle 6\ feet

Possible Answers:

\displaystyle \small 186cm^3

\displaystyle \small 192cm^3

 

\displaystyle \small 48cm^2

\displaystyle \small 32cm^3

Correct answer:

\displaystyle \small 192cm^3

 

Explanation:

To solve this problem we need to recall the formula for volume of a rectangular prism. The formula for volume of a rectangular prism is \displaystyle \small v=l\times w\times h

\displaystyle \small v=8\times4\times6

\displaystyle \small v=192cm^3

Remember, volume is always labeled as units to the third power. 

Example Question #2 : Measurement And Data

How many \displaystyle \textup{centimeters} are in \displaystyle 13\textup { meters?}

Possible Answers:

\displaystyle .0013\textup { centimeters}

\displaystyle 1.3\textup{ centimeters}

\displaystyle 1\textup,300\textup { centimeters}

\displaystyle 130\textup { centimeters}

Correct answer:

\displaystyle 1\textup,300\textup { centimeters}

Explanation:

To solve this problem we can make proportions.

We know that \displaystyle 1\ centimeter= .01\ meters and we can use \displaystyle x as our unknown. 

\displaystyle \frac{1\ centimeter}{.01\ meter}=\frac{x\ centimeters}{13\ meters}

Next, we want to cross multiply and divide to isolate the  on one side. 

\displaystyle 1\ centimeter\times 13\ meters=.01\ meter\times x\ centimeters

\displaystyle \frac{1\ centimeter\times 13\ meters}{.01\ meter}= x\ centimeters

The \displaystyle meters will cancel and we are left with \displaystyle 1,300\ centimeters
