How to solve
Like addition, subtraction of fractions requires matching piece sizes. Once both fractions share a denominator, subtract the numerators and simplify — the denominator stays the common unit size.
Steps
- Find a common denominator and rewrite both fractions.
- Subtract the numerators; keep the common denominator.
- Simplify the result to lowest terms.
Example
Compute 5/6 − 1/4.
- Common denominator: 12.
- Rewrite: 10/12 − 3/12.
- Subtract: 7/12.
Answer: 7/12
