Question: What is the smallest prime factor of the number formed by reversing the digits of 3920?

To find the number formed by reversing the digits of 3920, we get 0293. The smallest prime factor of 0293 is 293 itself, which is a prime number and cannot be factorized any further.

Math question: If 20% of 3920 is subtracted from its double, and the result is divided by 10, what is the final value?

To find the final value, we first calculate 20% of 3920, which is 784. Subtracting this from twice the initial value of 3920 (7840) gives us 7056. Now, if we divide this by 10, we get the final value of 705.6. Therefore, the final value is 705.6.

Question: How many times can the number 35 divide evenly into the number 3920?

To find the number of times 35 can divide evenly into 3920, we divide 3920 by 35: 3920 ÷ 35 = 112. Therefore, the number 35 can divide evenly into 3920 112 times.
