Answer 1

Solution:

we are given that

You have a large container of olive oil. You have used $22 \frac{1}{2}$ quarts of oil.

Twenty-five percent of the olive oil remains.

we have been asked to find how many quarts of olive oil remain?

Let there were x quarts of olive oil.

It mean , we can write

$x-22 \frac{1}{2}=\frac{1}{4}*x$

$x-\frac{1}{4}*x=22 \frac{1}{2}$

$\frac{3x}{4}=22 \frac{1}{2}$

$3x=4*22 \frac{1}{2}$

$x=\frac{4}{3}* \frac{45}{2}$

$x=30$

Hence quarts of olive oil remain $=30-\frac{45}{2}=\frac{15}{2}=7\frac{1}{2}$
