Math Question: In a classroom, there are 4090 students, divided into groups of 30. How many complete groups are formed, and how many students are left in the last group?

To find the number of complete groups, divide 4090 by 30 to get 136.3. Since groups cannot be fractional, there are 136 complete groups. To determine the remaining students, subtract the number of students in complete groups (136 * 30 = 4080) from the total number of students (4090). Thus, there are 10 students left in the last group.

Question: What is the sum of the digits in the number 4090?

To find the sum of the digits in the number 4090, we can add each digit together. The digit 4 has a value of 4, the digit 0 has a value of 0, the digit 9 has a value of 9, and the digit 0 has a value of 0. Adding these digits together (4+0+9+0), we get a sum of 13. Therefore, the sum of the digits in the number 4090 is 13.

Math question: What is the remainder when 4090 is divided by 9?

To find the remainder, we divide 4090 by 9. The quotient is 454 and the remainder is 4. Hence, when 4090 is divided by 9, the remainder is 4.
