Answer 1

A) The divisibility rule of 5 is that the number in the ones place should either have 0 or 5. Colour numbers red which end in 0 or 5

B) The divisibility rule of 2 is that the number in the ones place should either have 0, 2, 4, 6 or 8. Colour numbers green which end in 0, 2, 4, 6 or 8.

C) The divisibility rule of 3 is that all the digits in the number should add up to be a multiple of 3. Colour numbers blue which add up to a multiple of 3. Eg 123 =
1 + 2 + 3 = 6
6 comes in the table of 3 and thus 123 is a multiple of 3.
