When fractions have the same denominator, we simply add or subtract the numerators and keep the denominator the same - like 2/5 + 1/5 = 3/5.
Quick revision
Remember these!
- Same denominator: add/subtract numerators, keep denominator.
- 2/5 + 1/5 = 3/5.
- Different denominators: find common denominator first.
- 1/2 + 1/3 = 3/6 + 2/6 = 5/6.
- Simplify the answer after adding/subtracting.
- This skill applies to recipes and comparing portions.
- Practice builds confidence with fraction operations.
- Common denominators make addition/subtraction possible.
