To determine how many numbers between 1 and 90 are divisible by 3, we can use the formula for finding the number of integers in a range divisible by a certain number. The formula is (largest number - smallest number) / divisor + 1. In this case, the largest number is 90, the smallest number is 1, and the divisor is 3. Plugging these values into the formula, we get (90 - 1) / 3 + 1 = 30. Therefore, there are 30 numbers between 1 and 90 that are divisible by 3.
