SORRY FRIEND I DON'T KNOW ANSWER FOR LAST ONE

Answer 2

$1. \frac{1}{2} + \frac{1}{6}$

L. C. M = 6

$\frac{3 + 1}{6} = \frac{4}{6}$

If you want to reduce this then you can reduce

$2. \: \frac{1}{8} + \frac{3}{4}$

L. C. M = 8

$\frac{1 + 6}{8} = \frac{7}{8}$

$3. \: \frac{1}{7} + \frac{4}{ - 7}$

In this denominators are same so we will not take out the .L.C.M

$- \frac{ 1 + 4}{7} = \frac{3}{7}$
