Question

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

Answer 1

Finding the value of the expression

Given that, $m=\frac{1}{2}$ and $n=\frac{-3}{4}$

We have to find the value of expression $2m\times n$

Putting the value of $m$ and $n$ in given expression:

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

Hence, $-\frac{3}{4}$, is the required value of expression.
