Answer 2

We want 4 as denominator so we will have to multiply the denominator with a certain number by which we should multiply the numerator too.

So,

$\frac{3}{4} = \frac{3 \times x}{4 \times x} = \frac{3x}{20}$

Now let's focus on denominator....

$4 \times x = 20 \\ = = > x = \frac{20}{4} \\ = = > x = \dfrac{\cancel{20}} {\cancel{4}} \\ = = > x = 5$

So we will have to multiply numerator & denominator by 5

So,

$\frac{3}{4} = \frac{3 \times 5}{4 \times 5} = \frac{15}{20}$
