Mark (✓) against the correct answer
What per cent of $\frac{2}{7}$ is $\frac{1}{35}$?

(a) 25%
(b) 20%
(c) 15%
(d) 10%

Answer 1

(d) 10%

Let x be the required percent.
Then, x % of $\frac{2}{7}$ = $\frac{1}{35}$
⇒ $\left(\frac{x}{100}\times \frac{2}{7}\right)=\frac{1}{35}$
∴ x = $\left(\frac{100\times 7}{35\times 2}\right)$ = 10
Hence, 10% of $\frac{2}{7}$ is $\frac{1}{35}$
