Answer:

The addition of given fractions is $\frac{11}{12}$

Therefore $\frac{1}{4}+\frac{2}{3}=\frac{11}{12}$

To find the addition of given fractions :

Adding the given fractions we get

$\frac{1}{4}+\frac{2}{3}$

$=\frac{1(3)+2(4)}{12}$ ( here taking 12 as LCM )

$=\frac{3+8}{12}$

$=\frac{11}{12}$

Therefore $\frac{1}{4}+\frac{2}{3}=\frac{11}{12}$

The addition of given fractions is $\frac{11}{12}$
