Question

If $\frac{11}{17}$ and $\frac{a}{85}$ are equivalent fractions, what is the value of 'a' ?

• A. 52
• B. 53
• C. 54
• D. 55

Answer 1

The correct option is D 55

We get equivalent fractions when we multiply the numerator and the denominator by the same number.

Here $\frac{11}{17}$ and $\frac{a}{85}$ are equivalent fractions.

To get 85 we will multiply 17 by 5, hence to get 'a' we will also multiply 11 by 5.

$\frac{11\times 5}{17\times 5}$ = $\frac{55}{85}$

On comapring $\frac{a}{85}$ and $\frac{55}{85}$


Therefore a = 55
