We will use the divisibility shortcut rules to help us determine if the first number given is divisible by the second. It is divisible by 2 if it is even, divisible by 5 if it ends in 5 or 0, and divisible by 10 if it ends in zero. It is divisible by 3 if the sum of the digits is divisible by three, and divisible by 9 if the sum of the digits is divisible by nine. It is divisible by 6 if it is divisible by both 2 and 3.
