Question: how many numbers from 1 to 100 are divisible by 3?
Answer: Now, you have 100 divided by 3 = 33 + 1 remainder. This means that there are 33 numbers from 1 to 100 divisible by 3, but you have to pick only the odd ones, since you;ve already eliminated the even ones. The number off odd multiples of 3 between 1 and 100 will be 33/2 = 16 remainder 1.
