Question

Select all the options that have the same value as 3 1/2% of 20?

Answer 1

Solution:

As, we have to find , $3 \frac{1}{2} of 20=\frac{7}{2}$% of 20

$= \frac{7}{2\times 100}\times 20\\\\ = \frac{7}{10} \\\\ =0.70$

If we have to Percent of a certain number it means , divide that number by 100 , for example x% means $\frac{x}{100}$.

And if i am writing , x% of y it means ,   $\frac{xy}{100}$.
