**Multiply or Divide
**

**Use the rule to fill in the chart.**

Question 1.

Answer:

Explanation:

y = 3

=> y × 9 = 3 × 9 = 27.

y = 4

=> y × 9 = 4 × 9 = 36.

y = 5

=> y × 9 = 5 × 9 = 45.

Question 2.

Answer:

Explanation:

c = 5

=> c ×12 = 5 × 12 = 60.

c = 6

=> c ×12 = 6 × 12 = 72.

c = 7

=> c ×12 = 7 × 12 = 84.

Question 3.

Answer:

Explanation:

x = 50

=> x ÷ 5 = 50 ÷ 5 = 10.

x = 40

=> x ÷ 5 = 40 ÷ 5 = 8.

x = 30

=> x ÷ 5 = 30 ÷ 5 = 6.

Identify the rule that explains the chart.

Question 4.

Answer:

Division rule is used in the chart.

Explanation:

x = 120.

=> x ÷ ?? = 12

=> 120 ÷ ?? = 12

=> ?? = 120 ÷ 12

=> ?? = 10.

x = 100.

=> x ÷ ?? = 10

=> 100 ÷ ?? = 10

=> ?? = 100 ÷ 10

=> ?? = 10.

x = 80.

=> x ÷ ?? = 8

=> 80 ÷ ?? = 8

=> ?? = 80 ÷ 8

=> ?? = 10.

Question 5.

Answer:

Division rule is used in the chart.

Explanation:

y = 120.

=> y ÷ ?? = 11

=> 77 ÷ ?? = 11

=> ?? = 77 ÷ 11

=> ?? = 7.

y = 56.

=> y ÷ ?? = 8

=> 56 ÷ ?? = 8

=> ?? = 56 ÷ 8

=> ?? = 7.

y = 42.

=> y ÷ ?? = 6

=> 42 ÷ ?? = 6

=> ?? = 42 ÷ 6

=> ?? = 7.

Question 6.

Answer:

Multiplication rule is used in the chart.

Explanation:

c = 3

=> c × ?? = 6

=> 3 × ?? = 6

=> ?? = 6 ÷ 3

=> ?? = 2.

c = 6

=> c × ?? = 12

=> 6 × ?? = 12

=> ?? = 12 ÷ 6

=> ?? = 2.

c = 9

=> c × ?? = 18

=> 9 × ?? = 18

=> ?? = 18 ÷ 9

=> ?? = 2.
