Question

What are the possible values of A and B?

• A. A = 15, B = 45
• B. A = 45, B = 32
• C. A = 15, B = 32
• D. A = 15, B = 15

Answer 1

The correct option is C A = 15, B = 32

According to the commutative property of addition, when two or more numbers are added in any order, the sum remains the same.

Given, 15 + 45 + 32 = 45 + A + B

We can write the above as:

15 + 45 + 32 = 45 + 15 + 32 = 92

15 + 45 + 32 = 15 + 32 + 45 = 92

15 + 45 + 32 = 32 + 45 + 15 = 92

Therefore, possible values of A and B are 15 and 32 respectively.

So, option c is correct.
