Answer 2

Answer:

1: A) No

2: B) Yes, because the last digit in the number is 5

3: A) No

Step-by-step explanation:

For number one, check to see if the sum of the digits is divisible by 9, since that is the divisiblity rule for the number nine.

3+1+8=12

Is 12 divisible by 9? No, so the answer is A.

For number two, check to see if the last digit in the number is a five or a zero. If it is, it is divisible by 5. 87, 235 ends in a five, so it is divisible by five. So the answer is B.

For number three, check to see if the sum of the digits are divisible by three, since that is the divisibility rule for the number three.

4+3+1+2+1= 11

Is eleven divisible by 3? No, so the answer is A.
