Math question: If I divide a number by 5, subtract 20, multiply by 3, and add 15, the result is 3665. What is the number?

Let's denote the unknown number as x. Based on the given information, we can set up the equation as ((x / 5) - 20) * 3 + 15 = 3665. To solve this equation, we simplify the expression: (3/5)x - 60 + 15 = 3665, which yields (3/5)x - 45 = 3665. Next, we bring -45 to the other side of the equation: (3/5)x = 3665 + 45, giving (3/5)x = 3710. Finally, we isolate x by multiplying both sides by (5/3), resulting in x = (5/3) * 3710 = 6183.33 (approx.). Therefore, the unknown number is approximately 6183.33. Note: Since you requested an answer of up to 500 characters, I provided a brief explanation of the solution process. If you need further elaboration, please let me know!

Math question: If 3665 is divided by the product of the sum of its digits and its units digit, what is the quotient?

To find the units digit of 3665, we take the remainder when it is divided by 10, which is 5. The sum of the digits (3+6+6+5) equals 20. Multiplying 20 by the units digit 5 gives 100. Now dividing 3665 by 100, we find that the quotient is 36.65.

Math question: What is the sum of the digits of the number 3665?

To find the sum of the digits, we add up the individual digits in the number. In the case of 3665, the sum would be 3 + 6 + 6 + 5 = 20.
