40% of college students scored more than 70% on a math test. 120 students scored below that.

1 answer:

4 0

So if 40% of college students scored above 70%, then 60% of college students scored below 70%.

Our equation would be: 0.60x=120
x=120/0.60
x=12000/60
So x equal 200 students took the math test
