If 25 students took an exam and 4 of them failed, what percent of them passed?
lisabon 2012 [21]

If 25 students took an exam and 4 of the students that took the exam failed, what percent of the students passed?

To find out how many students passed, we can subtract 4 from 25 and we will get a difference of 21.

The fraction \frac{21}{25} represents the number of students who passed the exam out of all the students.

To find out what percent of the students passed, we can turn \frac{21}{25} into a percent.

21 ÷ 25 = 0.84

0.84 × 100 = 84%

Therefore, 84% of the students who took the exam passed.

Which is the greatest of these rational numbers?
mrs_skeptik [129]

Answer:

19/25

Step-by-step explanation:

Convert the two fractions into decimals by dividing the numerator by the denominator. 19/25 = 0.76 and 5/20 = 0.25

Now you have: 0.76, 0,680, 0.33 and 0.25.

0.76 is the greatest rational number because it is closest to 1.0, making 19/25 the correct answer.
