Question

List the set that satisfies the given condition: a positive multiple of 3 and less than 16.

Answer 1

Explanation:

in other words : any natural number, that is a multiple of 3 and less than 16.

what multiples of 3 do we know that are lower than 16 ?

3 × 1 = 3

3 × 2 = 6

3 × 3 = 9

3 × 4 = 12

3 × 5 = 15

3 × 6 = 18 already too large.

so, we have

{3, 6, 9, 12, 15}
