Math Question: If 20% of a number is 315, what is 30% of the number?

To find 30% of the number, we can use the proportion method. Let x be the number. Now, we know that 20% of x is equal to 315. So, we can set up the equation: (20%/100%) * x = 315. Simplifying, we get (1/5) * x = 315. Solving for x, we find x = 1575. To find 30% of the number, we can calculate (30%/100%) * x, which is (3/10) * 1575 = 472.5. Therefore, 30% of the number 1579 is 472.5.

Question: If the number 1579 is divided by a three-digit number, finding the remainder and then adding the quotient to the remainder, what is the smallest possible value of this sum?

To find the smallest possible value, we can divide 1579 by a three-digit number. Since the remainder added to the quotient gives the sum, we want to minimize both. By trial and error, dividing 1579 by 179 yields a quotient of 8 and a remainder of 117. So, adding 8 to 117 gives us the smallest sum of 125.

Math question: What is the sum of the digits in the number 1579?

To find the sum of the digits in 1579, we add the individual digits together. The number 1579 is composed of the digits 1, 5, 7, and 9. Adding them up: 1 + 5 + 7 + 9 equals 22. Hence, the sum of the digits in the number 1579 is 22.
