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.
The only number with a 6 between 1 and 9 is 6. Between 10 and 99, every number that ends in a 6 or is in the sixties will have a 6 in it. The former category has 9 numbers in it, the latter 10, but they overlap at 66 so there are 18 numbers total in the range. Fromm 100 to 999, the number must have a 6 in either the ones, tens, or hundreds digit. 90 numbers have a 6 in the ones place, 90 again in the tens place, and 100 in the hundreds place. NOT including the number 666, there are 8 overlaps that have 6 in both the ones and tens place, 9 with 6 in the ones and hundreds place, and 9 with 6 in the tens and hundreds place. Finally, the number 666 was counted an extra two time. Subtracting all the double/triple appearances, there are 252 numbers with a 6 in this range. Finally, add up all these ranges to get that there are 271 numbers numbers with the digit 6 in this range.
The 1 is in the tens place.
The 8 is in the tens place.
128.27 to the nearest tens place = 130

To find how many times the digit '3' appears between 300 and 400, we look at the numbers from 300 to 399. The hundreds place always has '3' for these numbers, contributing one '3' for each of the 100 numbers (300 to 399). Additionally, the '3' appears in the tens place in the numbers 330 to 339, contributing another 10 occurrences. In total, there are 1 (from the hundreds place) + 10 (from the tens place) = 11 occurrences of the digit '3' between 300 and 400.
To find how many times the digit 2 occurs in the tens place from 100 to 1000, we can analyze the range of numbers. The relevant range for the tens place is from 120 to 229, which includes all numbers where the tens digit is 2. This gives us the numbers 120-129 (10 occurrences), 220-229 (10 occurrences), totaling 20 occurrences of the digit 2 in the tens place.

Only one number between 0 and 60 has a two in the ones and tens place, and it's 22. However, if you are looking for all the numbers between 0 and 60 that have a two in EITHER the ones OR tens place, they are 2, 12, 21, 22, 23, 24, 25, 26, 27, 28, 29, 32, 42, and 52.
