About this printable
Practice simplifying ratios with eight focused exercises and a separate answer page. The questions are arranged in two columns with working space in each box. The article also includes the answers as readable text, so you can check a response without opening the solution image. Use the practice page first and keep the key aside until the learner has tried a method.
How to use it
A ratio compares quantities in a stated order. Dividing both parts by the same nonzero number preserves that comparison. For example, 12:18 simplifies to 2:3 because both parts can be divided by 6.
Check and adapt
Keep the original order: 2:3 and 3:2 describe different comparisons. After simplifying, check that the remaining parts have no common factor greater than one. This set uses positive whole-number pairs and asks for ratios rather than fractions of a total.
