Learning Objective
I can add fractions with unlike denominators by finding a common denominator.
- 1
To add fractions with unlike denominators, you must first find a common denominator.
- 2
The least common multiple of 2 and 3 is 6, so we can express ½ as 3/6 and ⅓ as 2/6.
- 3
When adding fractions with a common denominator, add the numerators and keep the same denominator, so 3/6 + 2/6 = 5/6.
