b. What is 39% of 200?
c. What is 150% of 32?
d. 13 is 50% of what number?
e. 18 is 120% of what number?
f. 21 is what percentage of 30?

Answer 1

Explanation:

a. 40 because 25 percent is 1/4th and 160 times 1/4=40

b. 78 because 200 times 39/100 is 78

c. 48 because 32 times 150/100=48

d. 26 because if it is 50 percent it is 1/2 of a number so just multiply

e. 15

f. 70 percent, simplify both numbers to the lowest number possible equal to 21/30 so 7/10 and that is 70 percent
