Question

3+(4+5) = ( 3+4 ) +5.THIS IS AN EXAMPLE OF THE ---------OF WHOLE

NUMBERS.
(a) COMMUTATIVE PROPERTY OF ADDITION.
(b) COMMUTATIVE PROPERTY OF MULTIPLICATION.
(c) ASSOCIATIVE PROPERTY OF MULTIPLICATION
(d) ASSOCIATIVE PROPERTY OF ADDITION.

Answer 1

D.

Explanation:

The problem is clearly addition, so we can rule out B and C. Associative property is the movement of the parentheses, whereas commutative property is the movement or reorganization of the numbers. The parentheses moved in this problem, so it is associative. I suggest reviewing these properites, they come in handy later and are good to know :)

Answer 2

(d) ASSOCIATIVE PROPERTY OF ADDITION.

Explanation:

"Associative Property Of Addition" means that in an addition expression; even if we make different groups with same given whole numbers, then also the sum in all the groups always remains the same. This property is also known as Associative property of Addition of Whole Numbers.

According to this question we were given:-

Group 1 = 3+(4+5) = 3+9 = 12

Group 2 = ( 3+4 ) +5 = 7+5 = 12

As, in both the groups the sum is same that is 12.

Therefore, whole numbers are associative under addition.
