# 51 is 340% of what?

Apr 3, 2017

15

#### Explanation:

I hope you know that if some number $a$ is some c% of a number $b$ then $\textcolor{red}{\frac{a}{b} \cdot 100 = c}$

Let $51$ be 340% of some number say $\textcolor{red}{x}$.

Then,

$\frac{51}{x} \cdot 100 = 340$

$\implies \frac{51}{340} \cdot 100 = x$

$\implies x = 15$

Hence $51$ is 340% of $15$.
