Math Question: What is the sum of the digits in the number 2870?

To find the sum of the digits in the number 2870, we add each individual digit together. The thousands digit is 2, the hundreds digit is 8, the tens digit is 7, and the units digit is 0. Adding these digits (2+8+7+0), we get the sum of 17. Therefore, the sum of the digits in 2870 is 17.

Math question: If a number is divisible by both 5 and 9, and it leaves a remainder of 6 when divided by 10, what is the largest three-digit number that satisfies these conditions?

To find the largest three-digit number that is divisible by both 5 and 9 and leaves a remainder of 6 when divided by 10, we need to find the LCM (Least Common Multiple) of 5 and 9, which is 45. Since the number leaves a remainder of 6 when divided by 10, we need to find a multiple of 45 that ends with 6. The largest such number is 2876, but we need to find the largest three-digit number, which is 1876. Hence, the largest three-digit number satisfying these conditions is 1876.

Math question: What is the sum of all prime numbers less than 2870 which are also divisible by 2, 3, and 5?

To solve this, we first find prime numbers less than 2870 that are divisible by 2, 3, and 5. After finding these numbers (i.e., 2, 5), we add them together. The sum comes out to be (2 + 5) = 7. Therefore, the answer is 7.
