Question

What should be added to $\frac{1}{4}$to get $\frac{4}{9}$?

Answer 1

Mathematical operation with fraction.

Let us consider $x$ being added to $\frac{1}{4}$to get $\frac{4}{9}$.

$$\begin{gathered} \therefore x+\frac{1}{4}=\frac{4}{9} \\ \Rightarrow x=\frac{4}{9}-\frac{1}{4} \\ \Rightarrow x=\frac{16-9}{36} \\ \Rightarrow x=\frac{7}{36} \end{gathered}$$

Hence, $\frac{7}{36}$ should be added to $\frac{1}{4}$to get $\frac{4}{9}$.
