Math question: How many times does the digit 7 appear in the numbers from 1 to 876 inclusive?

To count the occurrences of 7, consider the hundreds, tens, and units place separately. In the hundreds place, it appears 8 times (from 700 to 800). In the tens place, there are 10 possible options for 7 (70, 71, ..., 79) in each of the 10 blocks of hundreds, resulting in 100 total occurrences in the tens place. Finally, in the units place, for each 10-block of tens, there is exactly one occurrence (e.g., 77, 87, 97). Since there are 8 blocks of hundreds, a total of 80 occurrences appear. Adding these together, there are 8 + 100 + 80 = 188 occurrences of 7. Therefore, the digit 7 appears 188 times in the numbers from 1 to 876 inclusive.

Math question: What is the sum of the digits in the number 876?

To find the sum of the digits in 876, we add the individual digits together. Starting from the rightmost digit, we have 6 + 7 + 8 = 21. Therefore, the sum of the digits in 876 is 21.

Math question: What is the sum of the digits of 876 that are divisible by 3?

To find the digits of 876 divisible by 3, we add the individual digits: 8 + 7 + 6 = 21. Now, we check if 21 is divisible by 3, and it is. So, the sum of the digits of 876 that are divisible by 3 is 21.
