Answer: 1/3 + 2/3 = 1
Step-by-Step Solution
Step 1 Identify the Fractions

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

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

\frac{1}{3} + \frac{2}{3} = ?
Step 2 Same Denominators

Great! Both fractions already have the same denominator: 3

When denominators are equal, we simply add the numerators.

\frac{1}{3} + \frac{2}{3}
Step 3 Add the Numerators

Add the top numbers (numerators): 1 + 2 = 3

Keep the denominator the same: 3

\frac{1}{3} + \frac{2}{3} = \frac{1 + 2}{3} = \frac{3}{3}
Step 4 Simplify the Result

We can simplify by dividing both by their GCF (3).

Numerator: 3 ÷ 3 = 1

Denominator: 3 ÷ 3 = 1

\frac{3}{3} = \frac{1}{1}
