Answer:

Step-by-step explanation:

1/20=5%

2/20=10%

...

if the questions he got right equals x, and each question he got right equals 5%, than x/20=75% because he got 75% right.

now to solve it.

x/20=75%

percent means divided by 100 so

x/20=75/100

x/20*20=(75/100)*20

x=0.75*20

x=15

he got 15 questions correct
