Sixteen fractions to write in their simplest form, with denominators up to 24, such as 12/18 or 10/14. Divide the top and the bottom by a number that goes into both, and keep going until only 1 goes into both: 12/18 is 6/9, which is 2/3. Children who know their times tables find the biggest common factor in one step. The answer key gives the simplest form only.
