Question

There are 25 students in Laura's class, and 21 of the students went on the class trip to the zoo. What percentage of students went on the class trip?
(Explain for brainlist)

Answer 1

Answer: 84%

Step-by-step explanation:

A percentage is really a fraction with the denominator of 100. That means we can take the fraction of the students that went to the field trip (21/25) and make the denominator to 100. Since 25x4 is 100 we can do that but we also must do 21x4 because what you do to the top of the fraction you must do to the bottom. So you'd get 84/100 which is 84%

$\frac{21}{25}$ ×$\frac{4}{4} =\frac{84}{100}$

Answer 2

Since there are 25 students and there’s 21 at the zoo you would end up having 21 out of 25 and 21 out of 25 as a percentage is 84% because you have to look at 25 as a whole and that whole would be 100% so 84 out of 100% is equal to 21 out of 25
