51. if 4/5 of p is 48, what is 3/5

a. 12

b. 15

c. 20

d. 36

e. 60

When a equation uses 'of', it usually means multiplication and 'is' means equal.
4/5 x P= 48
However, you want to figure out what P is before answering 3/5.

(4/5)(P)=48   Divide 4/5 by both side

P=60

Then you want to find what 3/5 of P is. Since we know what P is, we can figure out the answer.

X= 3/5 (60)
x= 36 so the answer is D.
