Question

Write an equivalent fraction of $\frac{6}{7}$ with a denominator as $49.$

Answer 1

Let the numerator of equivalent fraction of $\frac{6}{7}$ be $\text{"x"}$.

Now, the question can be written as - $\frac{6}{7}=\frac{\text{x}}{49}$

By cross-multiplication method,

$$\begin{gathered} 7x=6\times 49 \\ x=\frac{6\times 49}{7} \\ x=6\times 7 \\ x=42 \end{gathered}$$

Hence, the equivalent fraction of $\frac{3}{4}$is $\frac{42}{49}.$
