About this worksheet

A fraction is in simplest form when the top and bottom share no factor except 1. The fastest way is to divide both by their greatest common factor: 15/21 shares a factor of 3, so it becomes 5/7.

Teaching tip

Students who divide by small factors one at a time (2, then 2 again) get there too. Just ask them to check that no factor is left at the end.
