Question
Find the number whose $12\frac{1}{2}\%\ $ is 64.
✓
Answer
Let the required number be x. Then,
$12\frac{1}{2}\times\text{x}=64$
$12.5\%\times\text{x}=64$
$\frac{12.5}{100}\times\text{x}=64$
$\text{x}=\frac{64\times100}{12.5}$
$=64\times8=512$
$\therefore\ \text{x}=512$
$12\frac{1}{2}\times\text{x}=64$
$12.5\%\times\text{x}=64$
$\frac{12.5}{100}\times\text{x}=64$
$\text{x}=\frac{64\times100}{12.5}$
$=64\times8=512$
$\therefore\ \text{x}=512$
