The least number of 4 digits which is exactly divisible by 9 is:
1 1018
2 1026
3 1009
4 1008
Explanation:
1008 Solution: Hence, 1018 is not exactly divisible by 9. 0 Hence, 1008 is exactly divisible by 9. (b) and (d) are exactly divisible by 9, but (d) is the least number which is exactly divisible by 9.

Which of the following depicts associative law for multiplication?
1 a + b = b + a
2 a × b = b × a
3 a + (b + c) = (a + b) + c
4 (a × b) × c = a × (b × c)
Explanation:
(a × b) × c = a × (b × c) Solution: Associative property for multiplication states that the product of any three or more numbers remains the same irrespective of the order in which the multiplication is carried out. \(\therefore\) (a × b) × c = a × (b × c).

Which is equal to (4 × 8) + (4 × 60)?
1 4 × (60 + 8)
2 8 × (60 + 4)
3 12 × (60 + 4)
4 16 × (60 + 8)
Explanation:
4 × (60 + 8) Solution: The distributive property of multiplication states that a number is multiplied by the sum of two numbers, when the first number can be distributed to both of those numbers and multiplied by each of them separately, then adding the two products together for the same result as multiplying the first number by the sum. So (4 × 8) + (4 × 60) = 4 × (8 + 60)
52, 53 Solution: Addition is associative for whole numbers. i.e. a + (b + c) = (a + b) + c \(\therefore \)52 + (53 + 55) = (52 + 53) + 55 \(\therefore\) The missing terms are 52,53.
