Question: What is the sum of the digits when the number 3975 is multiplied by 2, divided by 5, subtracted by 25, and finally divided by the difference between its tens and units digit?

To find the solution, we follow the given operations step by step. First, multiply 3975 by 2, resulting in 7950. Next, divide 7950 by 5, giving us 1590. Then, subtract 25 from 1590, which yields 1565. Lastly, we divide 1565 by the difference between the tens (7) and units digit (5) of the number 3975, resulting in 313. Therefore, the answer is 313.

Math question: If you multiply a number by 3975 and then divide the result by 2, how much is left when you subtract 100 from it?

Let's solve the problem step by step. If we multiply a number by 3975, we get 3975n. Now, if we divide the result by 2, we have 3975n/2. Subtracting 100 from this, we get 3975n/2 - 100. This expression gives us the amount left after the operations are applied. To calculate a specific value, we need a specific number 'n,' which we have not been provided. Therefore, we cannot determine a numerical answer without the value of 'n.' However, we have now set up the equation 3975n/2 - 100 to find the amount left after multiplying by 3975, dividing by 2, and subtracting 100 from it, once we know the value of 'n'.

Math question: What is the smallest prime number that is a multiple of 3975?

To find the answer, we start by dividing 3975 by prime numbers in ascending order. 3975 divided by 2 gives the quotient of 1987.5, which is not a whole number. Dividing 3975 by 3 results in the quotient of 1325. 3975 divided by 5 gives the quotient of 795, which is divisible by 3. Therefore, the smallest prime number that is a multiple of 3975 is 3.
