What's on this worksheet

Two proper fractions in simplest form with denominators from 2 to 12. Each sheet comes with an answer key on a separate page.

Teaching tips

  • Cross-simplify before multiplying to keep numbers small: in 4/9 × 3/8, divide 4 and 8 by 4, and 3 and 9 by 3.
  • Use an area model: 2/3 × 3/4 is the overlap of two shaded rectangles.
