Answer key · Set C
How many groups? How many in each?
16 Count the rings. There are 6 pots.
25 Look at one ring. It has 5 flowers, and every ring has the same.
36 3 groups with the same number in each make 18. 3 × 6 = 18.
45 Each group has 4 and there are 20 in all. 5 groups of 4 make 20.
5B 6 × 3 is 6 groups with 3 in each. A is 3 groups of 6, and C is only 4 groups.
64 3 plates with the same number make 12. 3 × 4 = 12.
78 3 groups with the same number make 24. 3 × 8 = 24.
8False The left one is 3 groups of 5 (3 × 5). The right one is 5 groups of 3 (5 × 3).
94 × 2, 2 + 2 + 2 + 2 There are 4 groups of 2. 4 × 2 and 2 + 2 + 2 + 2 both say it.
1023 4 × 5 = 20. Then 20 + 3 = 23.
1130 3 × 6 = 18 and 2 × 6 = 12. 18 + 12 = 30.
