30. One -fourth of a number is 17. What will be 45% of that number? A. 51 B 454 C. 38.6 D. 30.6 E

To solve this problem, we need to find the number first. Let's call the number "x". We are given that one-fourth of the number is 17, so we can write the equation:(1/4)x = 17To solve for x, we can multiply both sides of the equation by 4:x = 17 * 4x = 68Now that we have found the number, we can find 45% of it. To do this, we multiply the number by 0.45 (since 45% is equal to 0.45 as a decimal):45% of 68 = 0.45 * 680.45 * 68 = 30.6Therefore, 45% of the number is 30.6.The correct answer is D. 30.6.
