Comparing Fractions

Compare positive fractions using a visual model, equivalent fractions with a common denominator, or cross-products. Cross-products must be compared in the correct order.

Your goals

  • You can tell which fraction is bigger or smaller.
  • You can use common denominator, equivalent correctly.
  • You can use equivalent fractions, a model, or cross-products to confirm.

Words to know

common denominator:
A shared denominator used to compare or combine fractions.
equivalent:
Equal in value.

Examples

  • 12/5 and 3/5 have the same denominator, so 3/5 is greater because 3 > 2.
  • 2For 1/2 and 2/3, compare 1 × 3 = 3 with 2 × 2 = 4. Because 4 > 3, 2/3 is greater.

Check these

  • Do not compare denominators alone when the numerators differ.
  • Keep every number, symbol, label, and unit in its correct place.
  • Show enough working to check how you reached your answer.

Helpful habits

  • Read the whole question before choosing what to do.
  • Show one clear step at a time and check each step.
  • If you are stuck, draw a model, try smaller numbers, or revisit the example.

Now try your own

Create your own comparing fractions example, solve it, and explain how you checked it.
