Question

Solve the following:

$4-\frac{9}{5}$

Answer 1

Simplify the given expression by taking L.C.M:

Since, L.C.M of $1$ and $5$ is $5$.

So,

$$\begin{gathered} 4-\frac{9}{5} \\ =\frac{4\times 5-9}{5} \\ =\frac{20-9}{5} \\ =\frac{11}{5} \end{gathered}$$

Hence, $4-\frac{9}{5}$ is $\frac{11}{5}$
