Answer: 1/2 + 1/3 = \frac{5}{6}
Step-by-Step Solution
Step 1 Identify the Fractions

We need to add two fractions: 1/2 and 1/3

To add fractions, they must have the same denominator (bottom number).

\frac{1}{2} + \frac{1}{3} = ?
Step 2 Find the Least Common Denominator (LCD)

The denominators are different (2 and 3), so we need to find a common denominator.

The LCD is the smallest number that both 2 and 3 divide into evenly.

LCD = 2 × 3 = 6

\text{LCD}(2, 3) = 6
Step 3 Convert First Fraction

Multiply 1/2 to get denominator of 6:

Multiply both top and bottom by 3

\frac{1}{2} = \frac{1 \times 3}{2 \times 3} = \frac{3}{6}
Step 4 Convert Second Fraction

Multiply 1/3 to get denominator of 6:

Multiply both top and bottom by 2

\frac{1}{3} = \frac{1 \times 2}{3 \times 2} = \frac{2}{6}
Step 5 Add the Fractions

Now both fractions have the same denominator (6).

Add the numerators: 3 + 2 = 5

\frac{3}{6} + \frac{2}{6} = \frac{3 + 2}{6} = \frac{5}{6}
