Answer: 5/6 + 1/3 = \frac{7}{6}
Step-by-Step Solution
Step 1 Identify the Fractions

We need to add two fractions: 5/6 and 1/3

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

\frac{5}{6} + \frac{1}{3} = ?
Step 2 Find the Least Common Denominator (LCD)

The denominators are different (6 and 3), so we need to find a common denominator.

The LCD is the smallest number that both 6 and 3 divide into evenly.

Since GCD(6, 3) = 3, we calculate LCD = (6 × 3) ÷ 3 = 6

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

Multiply 5/6 to get denominator of 6:

Multiply both top and bottom by 1

\frac{5}{6} = \frac{5 \times 1}{6 \times 1} = \frac{5}{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: 5 + 2 = 7

\frac{5}{6} + \frac{2}{6} = \frac{5 + 2}{6} = \frac{7}{6}
Step 6 Convert to Mixed Number

Since 7 > 6, we can write this as a mixed number.

7 ÷ 6 = 1 remainder 1
\frac{7}{6} = 1\frac{1}{6}
