How come 135 is a multiple of 3?

Answer 1

There are many ways to answer this question. One way:

45 times 3 is 135 so 135 is a multiple of 3.

-- If you drop beans into a bag 3 at a time, there will

never be 134 or 136 beans in the bag, but there will be

a moment when there are exactly 135 beans in there.

-- If you divide 133 or 137 by 3, there will be a remainder,

because they're not multiples of 3. But if you divide 135 by 3,

there will be no remainder, because 135 is a multiple of 3.
