Math Question: If you divide 217 into two numbers such that the first number is 3 times the second number, and the sum of the two numbers is 63, what are the two numbers?

Let's assume the second number is x. Since the first number is 3 times the second number, it can be represented as 3x. We are given that the sum of the two numbers is 63, so we can form the equation: x + 3x = 63. Simplifying, we get 4x = 63. Dividing both sides by 4, we find x = 15.75. However, since the numbers can only be whole numbers, we round x to the nearest whole number, which is 16. Therefore, the second number is 16. To find the first number, we multiply 16 by 3, giving us 48. Hence, the two numbers are 48 and 16.

Math question: What is the largest prime factor of the number 217?

To find the largest prime factor of 217, we start by dividing it by the smallest prime number, 2. Since 217 is an odd number, we move on to the next prime number, 3. Dividing 217 by 3 gives us 72 with a remainder of 1. We continue dividing by 3 to get 24 with a remainder of 0. Now we divide by 3 again and get 8, again with no remainder. At this point, we can see that the largest prime factor of 217 is 3. To further verify this, we can divide 217 by 3 one more time to get 1. Therefore, 3 is the largest prime factor of 217.

Math question: What is the sum of the digits in the number 217 raised to the power of 3, divided by the difference between 217 and 2?

To solve this, let's break it down. First, we calculate the sum of the digits in 217: 2 + 1 + 7 = 10. Next, we raise this sum to the power of 3, meaning 10 × 10 × 10 = 1000. Moving on, we determine the difference between 217 and 2: 217 - 2 = 215. Finally, we divide the result from the previous step, 1000, by this difference: 1000 ÷ 215 = 4.6511627907. Thus, the answer is approximately 4.6511627907.
