Math ( Percents as Ratios)
posted by Dynasty .
Sue receives a test score of 75% on a test with 20 questions. How many did she get correct?
👉 I need help making these kinds of questions into proportions because I have a Benchmark Test (like a mid year test) coming up & I need to be able to set up these kind of porportions correctly. So someone PLEASE help me. I'm in 8th grade by the way.. so try to explain this to me in a way I will be able to understand. Thank you! ☺
Math ( Percents as Ratios) -
Percent out of 100 = number out of 20
75/100 = x/20
Cross multiply and solve for x.
100x = 1500
x = 15
