Question

A) 468% of what is 45.63

B) what number is 32.5% of 38.4

Answer 1

1. So we are trying to find what the base number is, and to do that we need to divide the amount by the percentage (in decimal form).

Percentage form to decimal form is just moving the decimal point 2 places to the left, which gives us in this case 4.68.

Now to divide: $\frac{45.63}{4.68} =9.75$

468% of 9.75 is 45.63

2. For this, we just need to multiply 32.5%(0.325 in this case) and 38.4.

$38.4 * 0.325=12.48$

12.48 is 32.5% of 38.4
