CPM Homework Help : MC1 Problem 4-10

Express each of the following lengths in feet.

Hint:

Remember that $12$ inches are equal to $1$ foot and $3$ feet are equal to $1$ yard. These conversions will come in handy!

$24$ inches

$18$ inches

$9$ inches

$2$ yards

$3$ inches

$2\frac{1}{2}$ yards

Hint 1 (a, b, & c):

Try drawing a diagram of how many inches are in a foot to compare to each of these measures.

Hint 2 (a, b, & c):

For instance, James converted $36$ inches to feet by drawing the diagram at right. He could see that there are $3$ groups of $12$ inches in $36$ inches, so that means $36$ inches is equal to $3$ feet!

Hint (d):

If one yard is $3$ feet, how many feet are in $2$ yards? Can you use multiplication? Why would that make sense?

Answer (e):

$3\text{ inches }=\frac{1}{4}\text{ feet.}$
