- Subtracting once denominators match
Worksheet Preview
Same-size pieces, then subtract
Just like adding, you can only subtract fractions when the pieces are the same size — so first rename both fractions over a common denominator, then subtract the numerators. For 1/2 − 1/4, rewrite 1/2 as 2/4 and subtract to get 1/4.
How to use it
Lean on equivalent fractions: find a common denominator, rewrite each fraction, then subtract. The classic error is subtracting straight across. Builds on adding fractions with unlike denominators.
👩🏫 Teacher note
You can only subtract pieces of the same size, so rename both fractions to a common denominator first, then subtract the numerators.
🏠 Parent note
Make the bottom numbers the same first (a common denominator), then subtract the top numbers.
Common Mistakes to Watch For
- Subtracting numerators and denominators straight across
- Using a common denominator but not converting the numerators
Answer Key
Each answer shows the difference; simplify where noted.
