Question

How many three digit numbers are divisible by 70?

Answer 1

Multiply 70 by something like 12 first since we know it will still be a 3 digit number:

70 * 12 = 840

Now, we can slowly increase it until it gets as high as it can without becoming 4 digits:

70 * 13 = 910

70 * 14 = 980

Because multiplying any higher will yield a number with over 3 digits, and 70 is not a 3 digit number (subtract 1 from the 14), there are 13 3 digit numbers divisible by 7.

Hope this helps! :)
