There are 20 students in a math class who have brown hair. This represents 80 percent of the students in the class. Which equation can be used to find the total number of students in the math class? StartFraction 20 times 100 Over 80 times 100 EndFraction = StartFraction 2000 Over 8000 EndFraction StartFraction 80 times 5 Over 20 times 5 EndFraction = StartFraction 400 Over 100 EndFraction StartFraction 80 divided by 4 Over 100 divided by 4 EndFraction = StartFraction 20 Over 25 EndFraction StartFraction 20 divided by 1 Over 80 divided by 1 EndFraction = StartFraction 20 Over 80 EndFraction
