Question
if $\frac{-5}{7}=\frac{\text{x}}{28}$ find the value of $x.$
✓
Answer
Given, $\frac{-5}{7}=\frac{\text{x}}{28}$
$\Rightarrow7\times\text{x}=-5\times28 [$by cross-multiplication$]$
$\Rightarrow\text{x}=-\frac{5\times28}{7}=-5\times4$
$\Rightarrow=-20$
Hence, the value of $x$ is $-20.$
$\Rightarrow7\times\text{x}=-5\times28 [$by cross-multiplication$]$
$\Rightarrow\text{x}=-\frac{5\times28}{7}=-5\times4$
$\Rightarrow=-20$
Hence, the value of $x$ is $-20.$
