Question

What number will replace '$*$' mark?

$\frac{4}{5}$$=$$\frac{*}{20}$

Answer 1

Given that the two fractions $\frac{4}{5}$and $\frac{*}{20}$ are equivalent fractions. Therefore, the two fractions when reduced to their simplest forms are equal.

So, reducing $\frac{4}{5}$ into its simplest form, we have

Since $\frac{4}{5}$is the simplest form. Therefore $\frac{*}{20}$is a fraction such that $\frac{*}{20}$$=$$\frac{4}{5}$

Hence, clearly for the fraction $\frac{*}{20}$ , the $*$ can be replaced by $16$.
