To solve these questions, you need to understand how to calculate percentages. Here's how you can find the answers to each question:
1. To find 45% of a number, you can set up the equation: 86 = 0.45n. Divide both sides of the equation by 0.45, and you will get n = 86 / 0.45. So the answer is 191.11 (rounded to the nearest whole number), which means 86 is 45% of 191.
2. To find what percent 4 is of 26, you can set up the equation: 4 = n x 26. Divide both sides of the equation by 26, and you will get n = 4 / 26. Then, multiply it by 100 to convert it to a percentage: n = 4 / 26 * 100. So the answer is approximately 15.38%. Therefore, 4 is approximately 15.38% of 26.
3. To find what percent 70 is of 250, you can set up the equation: 70 = n x 250. Divide both sides of the equation by 250, and you will get n = 70 / 250. Then, multiply it by 100 to convert it to a percentage: n = (70 / 250) * 100. So the answer is 28%. Therefore, 70 is 28% of 250.
4. To find 65% of 80, you can set up the equation: n = 65% x 80. Convert 65% to a decimal by dividing it by 100: n = 0.65 x 80. Multiply 0.65 by 80, and you will get n = 52. So 65% of 80 is 52.
5. To find what number 48 is 30% of, you can set up the equation: 48 = 0.30n. Divide both sides of the equation by 0.30, and you will get n = 48 / 0.30. So the answer is 160. Therefore, 48 is 30% of 160.
