Answer 2

$\fbox\red{A}\fbox\green{n}\fbox\blue{s}\fbox\orange{w}\fbox\purple{e}\fbox\green{r}$

LCM of 3 and 4 is 12.

Therefore,

$\sf\blue{ \frac{2}{3} + \frac{1}{4} = \frac{2 \times 4}{3 \times 4} + \frac{1 \times 3}{4 \times 3} }$

$\boxed{\sf\green{ = \frac{8}{12} + \frac{3}{12} = \frac{8 + 3}{12} = \frac{11}{12} }}$

Shortcut Method↓

$\sf\blue{ \frac{2}{3} + \frac{1}{4} = \frac{2 \times 4 + 1 \times 3}{12} = \frac{8 + 3}{12} = \frac{11}{12} }$
