Question

Which of the expressions below cannot be rewritten using the associative property?

A. 12 * (17 * 1)
B. 13 + 2 + 7
C. (15 + 4) + 10
D. (3 / 6) * 10

Answer 1

Option D
Because we are unable to bracket the only number without anything

Answer 2

Answer with Step-by-step explanation:

Associative property states that:

If a,b and c are three elements defined under an operation *

Then, (a*b)*c=a*(b*c)

A. 12 * (17 * 1)

Clearly in the above formula a=12, b=17, c=1 and *=*

12*(17*1)=(12*17)*1

B. 13 + 2 + 7

In the above formula a=13 ,b=2,c=7 and *=+

13+(2+7)=(13+2)+7

C. (15 + 4) + 10

In above formula a=15 ,b=4,c=10 and *=+

(15+4)+10=15+(4+10)

D. (3 / 6) * 10

This cannot be rewritten using the associative property
