🍕 How Do You Add Fractions?
5th Grade ➗ Math
To add fractions, the bottom numbers (denominators) must match. Then you add the top numbers.
Same denominators
If the bottom numbers are the same, just add the tops and keep the bottom: 1/5 + 2/5 = 3/5. Think of pizza slices that are all the same size.
Different denominators
If the bottoms are different, find a common denominator first. For 1/2 + 1/3, both 2 and 3 go into 6. 1/2 = 3/6 and 1/3 = 2/6, so the answer is 5/6.
Simplify at the end
Check if your answer can be simplified. 2/4 + 1/4 = 3/4, but 1/4 + 1/4 = 2/4, which simplifies to 1/2.
