To determine the number of 3-digit numbers that are multiples of 5, we need to find the first and last 3-digit multiples of 5. The first 3-digit multiple of 5 is 100, and the last 3-digit multiple of 5 is 995. To find the total number of such multiples, we can use the formula (Last - First) / 5 + 1 = (995 - 100) / 5 + 1 = 180. Therefore, there are 180 3-digit numbers that are multiples of 5.

JudyOh, dude, let me break it down for you. So, to find the number of 3-digit multiples of 5, you just gotta figure out the first and last numbers that are multiples of 5 in the 3-digit range, which are 100 and 995. Then you just do some simple math, like subtracting and dividing, and voila, you'll get your answer. It's like counting candy, but with numbers.
