Question

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

Answer 1

Step 1:Compute the required value.

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

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

$$\begin{gathered} 2m+n=2\left(\frac{1}{2}\right)+\left(\frac{-3}{4}\right) \\ =1-\frac{3}{4}=\frac{4-3}{4}\{takinL.C.M\} \\ =\frac{1}{4} \end{gathered}$$

$\frac{1}{4}$, is the required value of expression.

Hence, $\frac{1}{4}$, is the required value of expression.
