Question

12.5% of what number is 130

Answer 1

\[12.5\% \times x = 130 \\ \implies {12.5 \over 100} x = 130 \\ \implies 0.125x = 130 \]

Answer 2

Let the number be x

Answer 3

take a value: n

1 percent of n is just: n/100

12.5 of those 1 percents is: 12.5n/100

and that needs to equate to 130\[\frac{12.5n}{100}=130\]

Answer 4

12.5% = 130

Divide both sides by 12.5 to get 1%:
1% = 130/12.5 = 10.4

Multiply both sides by 100 to get 100%:
100% = 1040
