Elizabeth read 1920
of her book.
What percentage is equivalent to the fraction of the book that Elizabeth read?
Responses
A 80%80%
B 95%95%
C 75%75%
D 90%
To find the percentage equivalent of a fraction, you can divide the numerator (the number of parts you have) by the denominator (the total number of parts), and then multiply the result by 100.
In this case, Elizabeth read 1920 pages, and the total number of pages in the book is not given. Therefore, we cannot determine the fraction of the book that Elizabeth read, and therefore cannot determine the percentage equivalent.
Thus, none of the responses (A, B, C, D) can be the correct answer.

To find the percentage equivalent of a fraction, you can divide the numerator (the number of parts you have) by the denominator (the total number of parts), and then multiply the result by 100.
In this case, Elizabeth read 19 out of 20 parts of her book. To find the percentage, we can calculate:
(19 / 20) * 100 = 95%
Therefore, the correct answer is B: 95%.
Sofie earned $20 for helping her mom with her baby brother, Matthew. She spent $15 of the $20 on a board game.
What percent of the money did Sofie spend on the board game?
Responses
A 75%75%
B 25%25%
C 15%15%
D 60%60%
To find the percentage of the money Sofie spent on the board game, divide the amount she spent ($15) by the total amount she earned ($20), and then multiply the result by 100.
(15 / 20) * 100 = 75%
Therefore, Sofie spent 75% of the money on the board game. The correct answer is A: 75%.

D 115
To represent the amount of popcorn, in cups, a small popcorn holds, we can write it as a fraction with the given cup value as the numerator and 1 as the denominator.
Therefore, the fraction equivalent to 0.72 cup of popcorn is 72/100.
Simplifying this fraction, we can divide the numerator and denominator by their greatest common factor, which is 4:
72/100 = 18/25.
Thus, the fraction equivalent to the amount of popcorn a small popcorn holds is 18/25.
Therefore, the correct answer is B: 18/25.

To determine which set of numbers are equivalent, we need to compare each number and see if they represent the same value in their respective forms (decimal, fraction, and percentage).
A: 15, 0.2, 20%
B: 45, 0.4, 40%
C: 220, 0.01, 10%
D: 18, 0.8, 80%
We can evaluate each set:
- Set A: 15, 0.2, 20% - These numbers do not represent the same value because 15 and 0.2 are not equivalent to 20%.
- Set B: 45, 0.4, 40% - These numbers do not represent the same value because 45 and 0.4 are not equivalent to 40%.
- Set C: 220, 0.01, 10% - These numbers do not represent the same value because 220 is not equivalent to 0.01 or 10%.
- Set D: 18, 0.8, 80% - These numbers represent the same value. 18 is equivalent to 0.8 and 80%.
Therefore, the correct answer is set D: 18, 0.8, 80%.

- Set B: 65%, 0.65, 651000 - These numbers do not represent the same value because 0.65 and 651000 are not equivalent to 65%.
- Set C: 70%, 0.7, 7100 - These numbers do not represent the same value because 0.7 and 7100 are not equivalent to 70%.
- Set D: 95%, 0.95, 951000 - These numbers represent the same value. 0.95 is equivalent to 95% and 951000.
Therefore, the correct answer is set D: 95%, 0.95, 951000.
Martin was given 10 math problems, and he has answered 7 of them. What percent of the problems does Martin have left to do?
Responses
A 3%3%
B 7%7%
C 30%30%
D 70%
To find the percentage of problems Martin has left to do, we need to subtract the number of problems he has already done from the total number of problems, and then calculate that as a percentage of the total number of problems.
Martin has answered 7 problems out of 10, so the number of problems he has left to do is 10 - 7 = 3.
To find the percentage, we can calculate (3 / 10) * 100 = 30%.
Therefore, the correct answer is C: 30%.
