## McGraw-Hill Math Grade 4 Answer Key Chapter 3 Lesson 10 Multiplication and Division Patterns

Multiply or Divide
Use the rule to fill in the chart.
Question 1.

Explanation:
y = 3
=> y × 9 = 3 × 9 = 27.
y = 4
=> y × 9 = 4 × 9 = 36.
y = 5
=> y × 9 = 5 × 9 = 45.

Question 2.

Explanation:
c = 5
=> c ×12 = 5 × 12 = 60.
c = 6
=> c ×12 = 6 × 12 = 72.
c = 7
=> c ×12 = 7 × 12 = 84.

Question 3.

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.

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.

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.

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.
