Final answer:
To convert 0.252525... into a fraction, it is equivalent to 25/99. The number of questions Michael got right cannot be determined from the given decimal grade.
Step-by-step explanation:
To convert 0.252525... into a fraction, we can set it equal to x and subtract x from 100 times itself to eliminate the repeating decimal:
100x - x = 25.252525...
99x = 25
x = 25/99
So, 0.252525... is equivalent to the fraction 25/99.
To find out how many questions Michael got right out of the total number of questions on the exam, we need more information. The given decimal grade does not provide enough information to determine the number of questions.
