Question

Ve spent the whole weekend grading math assignments. I graded 30 students

work this weekend, which is 40% of my class. How many students do I have in
my class?

Answer 1

75

Explanation:

How many students is 1% of the class, 30/40=0.75, so you could do 0.75x100=75, or you could do 0.75x60=45, and 45+30=75.
