P.S. This is 6th Grade math on Edge 2020
Here are the options:
0 20 is 80% of what number?
0 20 × 4 = 80, so 100 × 4 = 400 students
0 20 + 60 = 80, so 100 + 60 = 160 students
0 80 ÷ 4 = 20, so 100 ÷ 4 = 25 students
0 80 – 60 = 20, so 100 – 60 = 40 students

Answer:

25

Step-by-step explanation:

80% got A orB out of 100% so

20 students are 80% of the class

we need 20% to find all 100% so

80%/4=20% and 20/4=5 students represent 20%

100%= 80%+20% =20students+5students=25 students
