1. To identify the part, whole, and percent in the statement "Find 15% of 750," we need to understand the components involved. The part refers to the portion being calculated, which is the result of finding 15% of 750. The whole is the total value that the percentage is based on, in this case, 750. The percent is the rate or ratio being applied to the whole.
To solve this problem, we can use the equation: part = percent x whole.
In this case, the part is what we are trying to find, so it can be represented by the variable n. The whole is 750, and the percent is 15. Therefore, we can identify the correct answer as option C.
2. To write a percent equation for the statement "820 is 20% of what number?" we need to determine the unknown number being referred to.
In this case, the unknown number is represented by the variable n. The given information states that 820 is 20% of that unknown number. This can be written in a percent equation as 820 = 0.2 x n. Therefore, the correct answer is option B.
3. To write a percent equation for the statement "25 is what percent of 350?" we need to find the unknown percent.
In this case, the unknown percent is represented by the variable p. The given information states that 25 is this unknown percent of 350. This can be written in a percent equation as 350 = p x 25. Therefore, the correct answer is option D.
4. To find the percent of questions Peggy answers correctly on a 40-question test, we need to divide the number of questions answered correctly by the total number of questions and then multiply by 100 to express the result as a percentage.
The number of questions Peggy answered correctly is given as 34 out of a total of 40. To calculate the percentage, we divide 34 by 40 and multiply by 100: (34/40) x 100 = 85%. Therefore, the correct answer is option A.
5. To find the percent of students on the student council out of a total of 75 students, we need to divide the number of students on the council by the total number of students and then multiply by 100 to express the result as a percentage.
The number of students on the student council is given as 15 out of a total of 75. To calculate the percentage, we divide 15 by 75 and multiply by 100: (15/75) x 100 = 20%. Therefore, the correct answer is option A.
