Question

ADDITION OF FRACTION
-2/5 + 3/4​

Answer 1

-2/5 + 3/4
-8+15/20
7/20 is the right answer

Answer 2

Take L.C.M of denominators 5 and 4

L.C.M = 20

Now make the denominators same

$\frac{ - 2}{5} \times \frac{4}{4} = \frac{ - 8}{20}$

$\frac{3}{4} \times \frac{5}{5} = \frac{15}{20}$

$\frac{ - 8}{20} + \frac{15}{20}$

$\frac{ - 8 \: + 15}{20}$

$\frac{7}{20} ans$
