80% of the students in Lea’s class earned an A or a B on the weekly math test. If 20 students got an A or a B, how many students are in Lea’s class? Will give Brainliest!!

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

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

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
