Let’s solve this step by step.
We are told:
Each plate has ten marbles.
So, for each group of plates, we just need to count how many plates there are — and then multiply that number by 10 (since each plate = 10 marbles).
---
First row:
- There are 2 plates.
- 2 × 10 =
20
Second row:
- There are 4 plates.
- 4 × 10 =
40
Third row:
- There are 3 plates.
- 3 × 10 =
30
Fourth row:
- There are 6 plates (3 on top, 3 on bottom).
- 6 × 10 =
60
---
Double-checking:
Row 1: 2 plates → 20 ✔️
Row 2: 4 plates → 40 ✔️
Row 3: 3 plates → 30 ✔️
Row 4: 6 plates → 60 ✔️
All correct.
Final Answer:
20
40
30
60
