Divide Fractions: Learn

To divide a fraction:

  • Invert the second fraction (that is, turn over or flip it)
  • Multiply just like any other fractions
  • Simplify the result, but do not convert to a mixed number unless the instructions say to do so

Inverting a fraction is also known as using its reciprocal.

Example: Divide 2/9 by 3/12

2
9
÷
3
12
=
2
9
*
12
3
=
2 * 12
9 * 3
=

9

Alternatively, you can cancel factors just before multiplying.

Example: Divide 2/9 by 3/12, but simplify the problem before multiplying, by canceling a factor of 3 out of the 9 and 12.
