Answer: 8
Step-by-step explanation: First, we can change this problem by saying 12.5% of what number is 8 since it means the same thing.
To answer the question 12.5% of what number is 8, we translate the question into an equation. First we have 12.5% which we need to write as a decimal and remember to write 12.5% as a decimal, we move the decimal point 2 places to the left. Filling in the missing position with a zero, we have 0.125.
Next we have "of what number" which means times x, "is 8" = 8.
Now we have the following equation.
(0.125)(x) = 8
Now to solve for x, since x is being multiplied by 0.125, we need to divide by 0.125 on both sides of the equation. On the left side of the equation the 0.125's cancel and we have x. On the right side of the equation we have 8 divided by 0.125 which is 64.
This means that 12.5% of 64 is 8.
