Let's go through the calculations one by one:
1. 18% of 90: To find 18% of 90, multiply 0.18 (the decimal equivalent of 18%) by 90. The calculation is 0.18 * 90 = 16.2. Your answer of 16.2 is correct.
2. 41% of 800: To find 41% of 800, multiply 0.41 (the decimal equivalent of 41%) by 800. The calculation is 0.41 * 800 = 328. Your answer of 328 is correct.
3. 5% of 522: To find 5% of 522, multiply 0.05 (the decimal equivalent of 5%) by 522. The calculation is 0.05 * 522 = 26.1. Your answer of 26.1 is correct.
4. 70% of 279: To find 70% of 279, multiply 0.7 (the decimal equivalent of 70%) by 279. The calculation is 0.7 * 279 = 195.3. Your answer of 195.3 is correct.
5. 90% of 13: To find 90% of 13, multiply 0.9 (the decimal equivalent of 90%) by 13. The calculation is 0.9 * 13 = 11.7. Therefore, your answer of 14.44 is incorrect. The correct answer is 11.7.
6. 9% of 351: To find 9% of 351, multiply 0.09 (the decimal equivalent of 9%) by 351. The calculation is 0.09 * 351 = 31.59. Round it to the nearest whole number, and you get 32. Therefore, your answer of 32 is correct.
7. 36% of 95: To find 36% of 95, multiply 0.36 (the decimal equivalent of 36%) by 95. The calculation is 0.36 * 95 = 34.2. Your answer of 34.2 is correct.
8. 56% of 48: To find 56% of 48, multiply 0.56 (the decimal equivalent of 56%) by 48. The calculation is 0.56 * 48 = 26.88. Therefore, your answer of 85.71 is incorrect. The correct answer is 26.88.
9. 96% of what number is 24: To find the number, divide 24 by 0.96 (the decimal equivalent of 96%). The calculation is 24 / 0.96 = 25. Therefore, your answer of 25 is correct.
10. 40% of what number is 30: To find the number, divide 30 by 0.4 (the decimal equivalent of 40%). The calculation is 30 / 0.4 = 75. Therefore, your answer of 75 is correct.
11. 36% of what number is 50.4? Let's solve for x: 0.36 * x = 50.4. Divide both sides by 0.36 to isolate x: x = 50.4 / 0.36 = 140. The number is 140.
12. 12% of what number is 72? Let's solve for x: 0.12 * x = 72. Divide both sides by 0.12 to isolate x: x = 72 / 0.12 = 600. The number is 600.
13. 12.8 is 32% of what number? Let's solve for x: 0.32 * x = 12.8. Divide both sides by 0.32 to isolate x: x = 12.8 / 0.32 = 40. The number is 40.
14. 684 is 95% of what number? Let's solve for x: 0.95 * x = 684. Divide both sides by 0.95 to isolate x: x = 684 / 0.95 = 720. The number is 720.
15. 72% of what number is 630? Let's solve for x: 0.72 * x = 630. Divide both sides by 0.72 to isolate x: x = 630 / 0.72 = 875. The number is 875.
