Record the product. Use expanded form to help.

Question 11.
5 × 64 = ___________
5 × 64 = 320.

Explanation:
The expanded form of 5 × 64 is
5 × 64 = 5 × (60+4)
= (5 × 60) +(5 × 4)
= 300+20
= 320.

Question 12.
3 × 272 = ___________
3 × 272 = 1,116.

Explanation:
The expanded form of 3 × 272 is
3 × 272 = 3 ×(300+70+2)
= (3 × 300)+(3 × 70)+(3 × 2)
= 900+210+6
= 1,116.

Estimate. Then record the product.

Question 17.
3 × 6 × 10 __________
3 × 6 × 10 = 180.

Explanation:
Here, Associative Property states that the product of three or more numbers remains the same regardless of how the numbers are grouped. So
3 × 6 × 10 = (3 × 6) × 10
= 18×10
= 180.

Question 18.
12 × 50 __________
12 × 50 = 600.

Explanation:
Here, Distributive property means if we multiply a sum by a number is the same as multiplying each addend by the number and adding the products. So
12 × 50 = (6+6)× 50
= (6× 50)+(6× 50)
= 300+300
= 600.

Question 19.
5 × 15 __________
5 × 15 = 75.

Explanation:
Here, Distributive property means if we multiply a sum by a number is the same as multiplying each addend by the number and adding the products. So
5 × 15 = 5 ×(10+5)
= (5 × 10)+(5 × 5)
= 50+25
= 75.

Question 20.
8 × 120 __________
8 × 120 = 960.

Explanation:
Here, Distributive property means if we multiply a sum by a number is the same as multiplying each addend by the number and adding the products. So
8 × 120 = 8 ×(100+20)
= (8 × 100)+(8 × 20)
= 800+160
= 960.

Question 21.
Sunset School had 4 performances of their school play during the first week. The auditorium can seat 2,518 people and all of the seats at each performance were filled. During the second week, 7,450 people attended the play. How many people saw the play during the two weeks?
(A) 10,072
(B) 4,932
(C) 9,968
(D) 17,522
C.

Explanation:
Given that the auditorium can seat 2,518 people and all of the seats at each performance were filled for first week and during the second week, 7,450 people attended the play, so the number of people saw the play during the two weeks is 2,518+7,450 which is 9,968 people.

Question 22.
The table below shows the number of calories in 1 cup of different kinds of berries. How many more calories are in 4 cups of blackberries than in 4 cups of strawberries? (A) 16
(B) 184
(C) 64
(D) 248
C.

Explanation:
Given that 1 cup of blackberries has 62 calories, so for 4 cups it will be 62×4 which is 248 calories. And 1 cup of strawberries has 46 calories, so for 4 cups it will be 46×4 which is 184 calories. So the number of more calories are in 4 cups of blackberries than in 4 cups of strawberries is 248-184 which is 64 calories.
