Question 17.
3 × 6 × 10 __________
Answer:
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 __________
Answer:
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.

(A) 16
(B) 184
(C) 64
(D) 248
Answer:
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.
