Answer : A
A. 3 × (2 × 6) = 36
we have 3 times 2 times 6. All the numbers have multiplication in between . so it comes under Associative property of multiplication.
B. (3 + 2) × 6 = 30
we have 3+2 . there is a + sign in between. so it does not comes under Associative property of multiplication
C. 6 + (5 × 6) = 36
we have 6 + . there is a + sign in between. so it does not comes under Associative property of multiplication
D. 3 × (2 + 6) = 24
we have 2 + 6 . there is a + sign in between. so it does not comes under Associative property of multiplication
