Question

if 20% of ms.moore's class earned a d how many of her 30 students earned a d what percent of students earned a different grade

Answer 1

6 students, 80% of students

Explanation:

20% of her 30 students earned a D. To find exactly how many students earned a D, we can convert the 20% into a fraction and thereby multiply the fraction by 30.

`20`%
`=`

`(20)/(100)=\\(1)/(5)`

Ok,
`(1)/(5)` of Ms. Moore's 30 students earned a D. Let's multiply.

`(1)/(5)*(30)/(1) =\\6`

6 students in Ms. Moore's class earned a D.

Therefore, the rest of the class earned a different grade.
`30-6=24` students had a different grade. To find the percentage, we simply divide by the total number of students and multiply by 100%

`(24)/(30) =\\(4)/(5) =\\0.8=`

`80`%

80% of students in Ms. Moore's class got a grade other than D.

I hope this helps! Let me know if you have any questions :)
