Question

Find the value of the following
1) what percentage of $50$ is $20$ ?
2) what percentage of $70$ is $35$?
3) what percentage of $100$ is $50$?
4) what percentage of $200$ is $80$?
5) what percentage of $160$ is $20$?

Answer 1

1) $\frac{20}{50}\times 100=40\%$

$20$ is $40\%$ of $50$

2) $\frac{35}{70}\times 100=50\%$

$35$ is $50\%$ of $70$

3) $\frac{50}{100}\times 100=50\%$

$50$ is $50\%$ of $100$

4) $\frac{80}{200}\times 100=40\%$

$80$ is $40\%$ of $200$

5) $\frac{20}{160}\times 100=\frac{200}{16}=12.5\%$

$20$ is $12.5\%$ of $160$
