48 students are girls , they make up 60% of the class how many total in class

total * 0.60 = 48

so

total = 48/0.6 = 80

there are 80 students in class

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

gdp is the best phrase!
