Poster Printing Supply Ratio Worksheet gives learners a diagram, one worked example and five questions. The student sheet leaves space to show work. A second printable page gives the steps for each answer.
Start with the model
Keep the relationship fixed by multiplying or dividing both quantities by the same number.
One batch pairs 4 posters with 8 sheets. The diagram shows a base pair, a doubled pair and two missing entries.
Worked example
Double the base pair 4 to 8. The equivalent pair is 8 to 16.
Ask the learner to point to the information used in the example. When they move on to the exercises, have them record the quantity, unit or label that each step represents.
Practice questions
- How many sheets go with 12 posters?
- How many posters go with 32 sheets?
- How many sheets go with one poster?
- Is 12 to 25 equivalent to 4 to 8? Explain.
- Combine batches of 8 and 12 posters. How many sheets are needed?
Separate answer key
- 12 is 3 times 4, so use 3 × 8 = 24 sheets.
- 32 ÷ 8 = 4 batches, so 4 × 4 = 16 posters.
- 8 ÷ 4 = 2 sheets per poster.
- No. Multiplying 4 by 3 requires multiplying 8 by 3, which gives 24, not 25.
- Together there are 5 batches, so 16 + 24 = 40 sheets.
