Question

$7\frac{1}{2}-2\frac{3}{4}=$ $4\frac{x}{4}$. Find x.

Answer 1

We have

$7\frac{1}{2}-2\frac{3}{4}=4\frac{x}{4}$

$\Rightarrow \frac{15}{2}-\frac{11}{4}=\frac{16+x}{4}$

$\Rightarrow \frac{30-11}{4}=\frac{16+x}{4}\left[L.C.Mof2\&4=4\right]$

$\Rightarrow 30-11=16+x\left[cancle4bothsides\right]$

$\Rightarrow 19=16+x$

$\Rightarrow x=19-16$

$\therefore x=3$

Hence, the value of $x=3$.
