Question

Find $12\frac{1}{2}$ percent of $64$ with an explanation.

Answer 1

Evaluate the percentage:

The given expression is,

$12\frac{1}{2}$ percent of $64$$=12\frac{1}{2}\%$ of $64$

We know that $x\%$ of $y=\frac{x}{100}\times y$.

Using this formula, we get,

$12\frac{1}{2}\%$ of $64=\frac{25}{2}\times \frac{1}{100}\times 64$

$=\frac{1}{2}\times \frac{1}{4}\times 64$

$=8$

Hence, the required value is $8$.
