Try a sample
A paint recipe uses 8 cups of blue for every 7 cups of white. Using 16 cups of blue at the same ratio, how many cups of white are needed?
- 35
- 42
- 7
- 14
See the answer & why
14
The blue amount is multiplied by 2; multiply white by the same factor: 7 × 2 = 14.
A little hint: Scale both parts of a ratio by the same factor.
A teaching tip
Find the scale factor and apply it to both ratio terms.
