Math question: What is the smallest prime number greater than 1375 that is divisible by both 3 and 5?

To find the smallest prime number greater than 1375 which is divisible by both 3 and 5, we need to analyze the multiples of 15 (3 * 5). Starting from 1380 (a multiple of 15 greater than 1375) and adding multiples of 15, we can observe that 1380, 1395, 1410, and 1425 are not prime numbers. However, 1440 is divisible by both 3 and 5 and is the smallest prime number greater than 1375 satisfying this condition. Thus, the answer is 1440, as it is the smallest prime number greater than 1375 that is divisible by both 3 and 5.

Math Question: If a number, when multiplied by 5 and then divided by 8, gives a result of 1718.75, what is that number?

To solve the equation (5x) / 8 = 1718.75, we first multiply both sides by 8 to isolate the variable: 5x = 13750. Then, to find x, we divide both sides by 5, giving us x = 2750. Therefore, the number is 2750.

Math Question: What is the sum of the digits of the number obtained by multiplying 1375 by the sum of its digits?

To find the sum of the digits, first add the digits of 1375: 1 + 3 + 7 + 5 = 16. Now multiply 1375 by 16, giving 22,000. To find the sum of its digits, we repeat the process: 2 + 2 + 0 + 0 + 0 = 4. Thus, the answer is 4.
