Math question: If a number is multiplied by 4 and then divided by 5, the result is 1525. What is the original number?

Let's solve the equation to find the original number. Let x represent the unknown number. We have the equation (4x)/5 = 1525. To isolate x, we multiply both sides by 5 and divide by 4, giving us x = (1525*5)/4. Simplifying, x = 1906.25. Therefore, the original number is 1906.25.

Math question: What is the sum of the digits of the number 1525?

To find the sum of the digits in 1525, we first break it down into its constituent digits. The digit 1 is in the thousands place, 5 in the hundreds place, 2 in the tens place, and 5 in the ones place. Hence, we have 1 + 5 + 2 + 5 = 13. Therefore, the sum of the digits in the number 1525 is 13.

Math question: If 1525 is divided by 5 and then multiplied by 7, what is the result?

To find the result, first, divide 1525 by 5, which gives you 305. Then, multiply 305 by 7 to get 2135. Therefore, the result is 2135.
