Ratio Table Worksheet Generator

About this tool

A ratio table lists pairs of numbers that all show the same relationship. If 2 cups of flour go with 3 cups of sugar, then 4 cups go with 6, and 10 cups go with 15. Students fill in the gaps by finding what the first column was multiplied by, then doing the same to the second row.

This generator builds those tables for you. You choose whole numbers, decimals or fractions, decide how many blanks to leave, and print. Every table is checked before it reaches the page: each column really does share one ratio, and no table leaves a student with a gap they cannot work out.

Use it for homework, a warm-up, a quiz, or a station activity. The mixed mode includes missing-value tables, proportional-or-not questions, and unit rate tables, so one sheet can cover a whole lesson.

How to use it

1. Choose a worksheet type. Missing values is the classic skill. The proportional option asks students to test every column. The unit rate option ends with the amount for one.
2. Set the number type and difficulty. Easier sheets use small whole numbers and two blanks. Harder sheets use bigger numbers, five columns and more blanks.
3. Switch between real-world labels such as cups of flour and cups of sugar, or plain x and y.
4. Press New worksheet for a fresh set. Use Show answer key to check it, and Print or save as PDF to print it. The answer key prints on its own page.
5. Use Copy link to send the exact same worksheet to a colleague or put it on a class page.

A worked example

Suppose a table shows 3 : 4 in the first column and 12 : ? in the last. Ask what 3 was multiplied by to reach 12. It was multiplied by 4, so the missing number is 4 × 4 = 16. A second way to check: the ratio of the second row to the first row is the same in every column, so 4 ÷ 3 should equal 16 ÷ 12. Both simplify to 4/3.

Students who add the same amount to both rows, going from 3 : 4 to 12 : 13, are making a very common mistake. Ratios grow by multiplying, not by adding.
