To find the answer:
1. Add the different parts of the ratio together (3+ 5 = 8)
2. Divide the number of rolls by the parts of the ratio that were added together (72 ÷ 8 = 9)
3. Now multiply that number first by 3, which is the first part of the ratio (9 × 3 = 27)
4. Then do the same but multiply the number by 5, the second part of the ratio (9 × 5 = 45)
You've got your answer! 27 and 45
