Complete the Ratio Table: Step-by-Step Example
27 October 2026
Ratio tables help children see the link between numbers in a ratio. This skill is important for 11+ maths and helps your child spot patterns quickly. If your child is practising with resources like maths.com uk, understanding ratio tables will make these questions much easier.
Worked example
Here is a ratio table for the ratio 3:5. Fill in the missing number.
| A | B | |-------|-------| | 3 | 5 | | 6 |? |
Step 1: Look at the first row. The numbers are 3 and 5.
Step 2: In the second row, A is 6. How did we get from 3 to 6? We multiplied by 2.
Step 3: Now do the same for B. Multiply 5 by 2.
5 × 2 = 10
Step 4: Write 10 in the table for B in the second row.
Key insight: In a ratio table, always multiply or divide both numbers by the same amount.
The completed table is:
| A | B | |-------|-------| | 3 | 5 | | 6 | 10 |
The answer is 10.
| A | B |
|---|---|
| 3 | 5 |
| 6 | 10 |
After this example, your child will recognise that both numbers in a ratio must be changed by the same amount. This builds confidence for similar questions, so they can practise completing ratio tables on their own next time.
