Question

Help, please

Thirty percent of a number is 8.4. What is 37.5% of the same number, a decimal to the nearest tenth?

Answer 1

Answer: 10.5 is my guess

Explanation:

1. 30% = 8.4

100 x

cross multiply

30(x) = 840

divide both sides by 30 = 28

2. 37.5% = y

100 28

cross multiply

1050 = 100y

divide both sides by 100 = 10.5
