Question

Express $\frac{2}{5}$ as a rational number with numerator :

$-56$

Answer 1

In the fraction $\frac{2}{5}$ the numerator is equal to $2$ and we want that numerator to be equal to $-56.$

Let we will have to multiply $x$ in the numerator and the denominator of the fraction $\frac{2}{5}$ to make numerator equal to $-56.$ So,

$2\times x=-56$

$\Rightarrow x=-28$

Hence,

$\begin{array}{cc}\frac{2}{5}& =\frac{2\times -28}{5\times -28}\\ & \\ & =\frac{-56}{-140}\end{array}$
