Answer 1

When dividing by a certain number gives a whole number answer. Example: 15 is divisible by 3, because 15 ÷ 3 = 5 exactly. But 9 is not divisible by 2 because 9 ÷ 2 is 4 with 1 left over

Answer 2

Answer:

Numbers which are divisible by both 2 and 3 are divisible by 6. That is, if the last digit of the given number is even and the sum of its digits is a multiple of 3, then the given number is also a multiple of 6. Example: 630, the number is divisible by 2 as the last digit is 0.

Numbers are divisible by 3 if the sum of all the individual digits is evenly divisible by 3. For example, the sum of the digits for the number 3627 is 18, which is evenly divisible by 3 so the number 3627 is evenly divisible by 3
