Question

The long jump pit at Martha's middle school is 9 1/3 feet long. Martha used rope to mark off a practice pit in her backyard, but she only had space to make one that was 3/4 as long. How long was Martha's practice pit?

Answer 1

Answer:

Martha's pit was 7 feet long.

Step-by-step explanation:

Given:

The long jump pit at Martha's middle school is 9 1/3 feet long.

Martha used rope to mark off a practice pit in her backyard, but she only had space to make one that was 3/4 as long.

Now, to find the length of Martha's practice pit.

The length of Martha's school pit = $9\frac{1}{3} =\frac{28}{3} \ feet.$

And the length of practice pit of Martha is = $\frac{3}{4}\ of\ \frac{28}{3} \ feet.$

Now, to get the length of Martha's practice pit:

$\frac{3}{4}\ of\ \frac{28}{3} \ feet.$

= $\frac{3}{4} \times \frac{28}{3}$

$=\frac{84}{12}$

$=7\ feet.$

Therefore, Martha's pit was 7 feet long.
