Math question: If the number 1485 represents the sum of three consecutive whole numbers, what are these three numbers?

Let's assume the middle number is n. According to the formula for the sum of arithmetic sequences, the sum of three consecutive numbers can be expressed as n-1 + n + n+1 = 1485. This simplifies to 3n = 1485. Dividing by 3, we get n = 495. Hence, the three consecutive whole numbers are 494, 495, and 496. Thus, the solution is 494, 495, 496.

Math question: What is the smallest prime number that can be evenly divided by 1485?

To find the answer, we need to examine the factors of 1485, which are 1, 3, 5, 9, 15, 27, 45, 81, 135, 405, and 1485. However, none of these factors are prime numbers except for 3 and 5. Therefore, the smallest prime number that can evenly divide 1485 is 3.

Math question: If the number 1485 is divided by 15 and then multiplied by 9, what is the result?

To find the result of dividing 1485 by 15, we get 99. Multiplying 99 by 9 gives us 891. Therefore, when 1485 is divided by 15 and then multiplied by 9, the result is 891.
