how many three digit numbers are divisible by 7

There are a total of 128 three-digit numbers that are divisible by 7.

To find this answer, we can use the formula for finding the number of integers divisible by a certain number within a given range. In this case, we want to find the number of three-digit numbers divisible by 7.

The largest three-digit number is 999, and the smallest three-digit number is 100. To find the number of integers divisible by 7 within this range, we can subtract the smallest number from the largest number and then divide the result by 7.

(999 – 100) / 7 = 899 / 7 = 128

Therefore, there are 128 three-digit numbers that are divisible by 7.
