Add Fractions

Same bottoms, different bottoms, and spotting the easy route.

How it works

  • 1If the denominators match, add the tops and keep the bottom.
  • 2If they don't match, make them match first — multiplying the two denominators always works.
  • 3Sometimes one denominator already fits into the other. Use it and save yourself the big numbers.

Worked example

3/8 + 1/4
1/4 = 2/8
3/8 + 2/8 = 5/8
