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

6 students, 80% of students

Step-by-step 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.

%

Ok, of Ms. Moore's 30 students earned a D. Let's multiply.

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

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

%

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