To add fractions, you need a common denominator.

Find the least common multiple (LCM) of the denominators 3 and 4.
The multiples of 3 are 3, 6, 9, 12, 15, ...
The multiples of 4 are 4, 8, 12, 16, ...
The LCM of 3 and 4 is 12.
Convert each fraction to an equivalent fraction with a denominator of 12.
For $\frac{1}{3}$ : Multiply the numerator and denominator by 4.
$\frac{1}{3} = \frac{1 \times 4}{3 \times 4} = \frac{4}{12}$
For $\frac{1}{4}$ : Multiply the numerator and denominator by 3.
$\frac{1}{4} = \frac{1 \times 3}{4 \times 3} = \frac{3}{12}$
Add the new fractions with the common denominator.
$\frac{4}{12} + \frac{3}{12} = \frac{4 + 3}{12} = \frac{7}{12}$
The sum is $\frac{7}{12}$ .
