Question

If $m=\frac{1}{2}$ and $n=\frac{-3}{4}$, find the value of: $m\times 4n$

Answer 1

Step 1: Given expression: $m\times 4n$ and $m=\frac{1}{2}$ and $n=\frac{-3}{4}$

We will put the value of $m$ and $n$ in given expression:

$$\begin{gathered} m\times 4n=\left(\frac{1}{2}\right)\times 4\left(\frac{-3}{4}\right) \\ =\left(\frac{1}{2}\right)\times -3 \\ =-\frac{3}{2} \end{gathered}$$

$-\frac{3}{2}$, is the required value of expression.

Hence, $-\frac{3}{2}$ is the required value of expression.
