Academic Mathematics NCERT Class 8

Given:

The sum of fractions $\frac{3}{4}, \frac{a}{4}$ is equal to $\frac{1}{4}$.

To do:

We have to find the unknown numerator $a$.

Solution:

$\frac{3}{4}+\frac{a}{4}=\frac{1}{4}$

$\frac{3+a}{4}=\frac{1}{4}$

Comparing the numerators on both sides, we get,

$3+a=1$

$a=1-3$

$a=-2$

The value of $a$ is $-2$.
