  • 21 baskets
  • 49 baskets
3.The orchard’s small and large fruit boxes are packed in the ratio 5:8. There are 65 small boxes. How many large boxes are there?

Ratios in the packing shed

Use equivalent ratios and proportional reasoning to help the team prepare orders.

4.Cooper packs 6 crates in 18 minutes at a steady rate. How many crates can he pack in 45 minutes?
