What numbers divisible by 9?
ANSWER:The numbers that are divisible by 9 are the numbers whose sum of the digits is a multiple of 9Example:27 = 2 + 7 = 9 (9 is a multiple of 9 thus 27 is divisible by 9)99 = 9 + 9 = 18 (18 is a multiple of 9 thus 99 is divisible by 9)
Are all numbers that are divisible by 9 also divisible by 3 are all numbers that are divisible by 3 also divisible by 9 how do you know?
All numbers divisible by 9 are divisible by 3; since 9 = 3 x 3 all multiples of 9 are also multiples of 3. However, all numbers divisible by 3 are not divisible by 9, eg 6 = 2 x 3 but 6 is not divisible by 9 (since 6 is not a multiple of 9) - it only takes one counter example to disprove a theory.
