select the correct choice below and fill in any answer boxes to complete your choice

The number is divisible by 3.
Why?
Add the digits in a number together, continuing onwards until you get a 1 digit number. If this number is a multiple of 3 (3, 6, or 9), it means the original number is as well.
Try it with this number.
7 + 5 = 12
1 + 2 = 3
3 is a multiple of 3 (3*1), so 75 is divisible by 3.
Check:
75/3 = 25
25*3 = 75

7p=14 so then you would divide by p=2
