Twenty-one fractions to write in simplest form, from easy ones like 4/8 to bigger ones like 36/48. Every fraction can be simplified, and the answer key gives the lowest-terms result.
Two ways to work: divide the top and bottom by the greatest common factor in one step, or divide by small numbers (2, 3, 5) again and again until nothing else works. Simplifying is the last step of almost every fraction problem from 4th grade on, so it pays to make it fast. Next, put it to use in adding and subtracting fractions.
Tips for using it
- Try 2 first (both even?), then 3 (digits add to a multiple of 3?), then 5 (ends in 0 or 5?).
- A fraction is in simplest form when 1 is the only number that divides both parts.

Questions
What does simplest form mean?
The numerator and denominator have no common factor except 1. 6/8 isn't in simplest form because both divide by 2; 3/4 is.
Is simplifying the same as reducing?
Yes. Reducing, simplifying and writing in lowest terms all mean the same thing. The fraction's value doesn't change.
