What is 12.5 of what number is 35

Answer 1

12.5 x = 35. 12.5 of what number is translated to
12.5 times x and the word "is" means equals. So 12.5x=35
x=2.8

Answer 2

well 12.5% of x = 35

so change it to a fraction

\[\frac{12.5 \times x}{100} = 35\]

make x the subject...

then

\[12.5 \times x = 3500\]

\[x = 3500 \div 12.5\]

hope it helps

an alternate method is change the percentage to a decimal

0.125x = 35

x = 35/0.125
