**

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

Question 1.

Answer:

Explanation:

y = 3

=> y Ã— 9 = 3 Ã— 9 = 27.

y = 4

=> y Ã— 9 = 4 Ã— 9 = 36.

y = 5

=> y Ã— 9 = 5 Ã— 9 = 45.

Question 2.

Answer:

Explanation:

c = 5

=> c Ã—12 = 5 Ã— 12 = 60.

c = 6

=> c Ã—12 = 6 Ã— 12 = 72.

c = 7

=> c Ã—12 = 7 Ã— 12 = 84.

Question 3.

Answer:

Explanation:

x = 50

=> x Ã· 5 = 50 Ã· 5 = 10.

x = 40

=> x Ã· 5 = 40 Ã· 5 = 8.

x = 30

=> x Ã· 5 = 30 Ã· 5 = 6.

Identify the rule that explains the chart.

Question 4.

Answer:

Division rule is used in the chart.

Explanation:

x = 120.

=> xÂ Ã·Â ?? = 12

=> 120 Ã· ?? = 12

=> ?? = 120 Ã· 12

=> ?? = 10.

x = 100.

=> xÂ Ã·Â ?? = 10

=> 100 Ã· ?? = 10

=> ?? = 100 Ã· 10

=> ?? = 10.

x = 80.

=> xÂ Ã·Â ?? = 8

=> 80 Ã· ?? = 8

=> ?? = 80 Ã· 8

=> ?? = 10.

Question 5.

Answer:

Division rule is used in the chart.

Explanation:

y = 120.

=> yÂ Ã·Â ?? = 11

=> 77 Ã· ?? = 11

=> ?? = 77 Ã· 11

=> ?? = 7.

y = 56.

=> yÂ Ã·Â ?? = 8

=> 56 Ã· ?? = 8

=> ?? = 56 Ã· 8

=> ?? = 7.

y = 42.

=> yÂ Ã·Â ?? = 6

=> 42 Ã· ?? = 6

=> ?? = 42 Ã· 6

=> ?? = 7.

Question 6.

Answer:

Multiplication rule is used in the chart.

Explanation:

c = 3

=> c Ã— ?? = 6

=> 3 Ã— ?? = 6

=> ?? = 6 Ã· 3

=> ?? = 2.

c = 6

=> c Ã— ?? = 12

=> 6 Ã— ?? = 12

=> ?? = 12 Ã· 6

=> ?? = 2.

c = 9

=> c Ã— ?? = 18

=> 9 Ã— ?? = 18

=> ?? = 18 Ã· 9

=> ?? = 2.
