Alicia got 60 questions correct on her science test. If she received a score of 75% , how many questions were on the test?????

Answers

so since 60=75%
here's a hack. it's not real math
just find a factor of 100 like 2,4,5,10,20,25, or 50
75=3*25

so 60=3*20
3*20=3*25
divide both sides by 3
20=25%
we know that 25% is 1/4 of 100 so
multiply both sides by 4
80=100%
