Find the sum $ \frac{5}{9}+\frac{7}{12} $.

Academic Mathematics NCERT Class 6

Given:

\( \frac{5}{9}+\frac{7}{12} \).

To do:

We have to find the sum \( \frac{5}{9}+\frac{7}{12} \).

Solution:

$\frac{5}{9}+\frac{7}{12}$

LCM of 9 and 12 is 36.

Therefore,

$\frac{5}{9}+\frac{7}{12}=\frac{5\times4+7\times3}{36}$

$=\frac{20+21}{36}$

$=\frac{41}{36}$

Therefore, the sum is $\frac{41}{36}$ .
