Answer:
175%
Explanation:
A percent is nothing but writing a term as a fraction with denominator only 100.
For example, 1/2 = 50/100 = 50%
and 2 =2/1=200/100 = 200%
Like this we calculate percentage.
In our problem a school has 4 quarters.
This means 4 quarters is equivalent to 100 percent
Our question is to find percent for 7 quarters
Since it is direct variation we calculate by 7(100)/4
=700/4= 175%
Hence answer is 175
