= / 21 + / 21
= (14 + 9) / 21

= / 21
2- 1 3
/ 6 + / 8
Solution:
The LCM (least common multiple) of the denominators 6 and 8 is 24.
So, we convert the given fractions into equivalent fractions with denominator 24.
We have,
4
1
= / 6 = (1 × 4) / (6 × 4)= / 24 [since 24 ÷ 6 = 4]
3
9
and, / 8 = (3 × 3) / (8 × 3) = / 24 [since 24 ÷ 8 = 3]

Thus, / 6 + / 8 = / 24 + / 24
= (4 + 9) / 24
