Final answer:
The correct answer is D. 30/54, which represents the fraction of the math assignment that Sabrina completed by multiplying 5/9 by the total number of problems, 54.
Step-by-step explanation:
The correct answer is option D. 30/54. To find the fraction representing the number of problems Sabrina completed, we need to find how many problems she has done. Since she finished 5/9 of her assignment and there are 54 problems in total, we multiply 5/9 by 54 to get the number of problems she completed:
5/9 of 54 = (5/9) × 54 = 5 × 6 = 30.
Therefore, Sabrina completed 30 out of 54 problems, and the fraction representing this is 30/54. This fraction can be simplified to 5/9 by dividing both the numerator and the denominator by 6, but since this option is not given, we stick to 30/54 as it is equivalent to the fraction of the assignment she completed.
The correct answer is option D. 30/54. To find the fraction that represents the number of problems completed over the total number of problems, we need to divide the number of problems completed by the total number of problems.
Sabrina completed 5/9 of her math assignment, which means she completed 5 out of 9 parts of her assignment. Since there are 54 problems in her assignment, we can find the number of problems completed by multiplying 5/9 by 54: (5/9) * 54 = 30.
Therefore, the fraction that represents the number of problems completed over the total number of problems is 30/54.
