Question

Sara’s English test had 90 questions and she got 18 questions wrong. What percent of the questions did she get correct?

Answer 1

80%

Explanation:

10%= 9

20%= 18

18= how many they got wrong

90=total questions

90= 100%

18= 20%

100%=20%=80%

Answer 2

80%

Explanation:

First we find the percentage she got wrong:

`(18)/(90)` Is the fraction she got wrong, now we convert this into a percentage by divding 18 by 90 and multiplying by 100

18÷90×100=20

so to find the remaining percent we subtract 20 from 100

100-20=80

And our answer is 80
