Answer 1

Answer:

A = 3

Step-by-step explanation:

We know that the sum of the numbers in a number divisible by 9 always adds up to a multiple of 9. Therefore, I used a small trick with no verified method

31A2 consist of the numbers, 3, 1, A, 2. For this number tp be divisible by 9 their sum must be equal to a multiple of 9.

3 + 1 + A + 2 = 9

6 + A = 9

A = 3

3132/9 = 348

This should be the answer.

Best of luck!
