How many numbers there between 200 and 500 that have 7 in the tens place?

Answer 1

To determine how many numbers between 200 and 500 have a 7 in the tens place, we need to consider the possibilities for the hundreds and units digits. Since the hundreds digit can be any number from 2 to 4 (inclusive), there are 3 options. The tens digit must be 7, and the units digit can be any number from 0 to 9, giving us 10 options. Therefore, the total number of numbers meeting this criteria is 3 (options for hundreds) x 1 (fixed digit in tens place) x 10 (options for units) = 30.

Answer 2

Oh, what a happy little question! Let's see here... We start at 200 and end at 499, so we have a total of 300 numbers in that range. Now, how many of those numbers have a 7 in the tens place? Well, we have 70, 71, 72, 73, 74, 75, 76, 77, 78, and 79, so that's 10 numbers. Just 10 little numbers dancing around with a 7 in the tens place!

Answer 3

Oh, dude, let me break it down for you. So, between 200 and 500, you've got 30 numbers in total, right? And if we're looking for numbers with 7 in the tens place, that's like 70-79, 170-179, and 270-279. So, there are 3 numbers in that range that fit the bill. Easy peasy lemon squeezy.
