How many 3 digit numbers are divisible by 7 and are a multiple of 7?

Answer 1

- The smallest one is 105 ... the 15th multiple of 7 .

- The biggest one is 994 ... the 142nd multiple of 7 .

- So the multiples of 7 that are between 100 and 999 are #15 through #142 ... 128 of them .

That answers half of your question. Now, in order to answer the other half,

here's something that's so simple it'll blow your mind:

- Every number that's divisible by 7 is a multiple of it,

and every multiple of 7 is divisible by it.

- And the same is true of any other number.

So as soon as we read your question, we know immediately that both answers

are going to be the same number.
