Question

Latasha earned 18 points on her quiz. If 24 points is equivalent to a score of 100% what two proportions could she use to calculate her percent score?

Answer 1

Explanation:

Given:

18 points on her quiz

24 points is equivalent to 100%

18 is to 24 or 18/24

x is to 100% or x/100%

18/24 = x/100%

18 * 100% = 24x

1800% = 24x

1800%/24 = x

75% = x

18/24 = 75%/100%

18 * 100% = 24 * 75%

1800% = 1800%

Answer 2

Given:
18 points on her quiz
24 points is equivalent to 100%

18 is to 24 or 18/24
x is to 100% or x/100%

18/24 = x/100%

18 * 100% = 24x
1800% = 24x
1800%/24 = x
75% = x

18/24 = 75%/100%
18 * 100% = 24 * 75%
1800% = 1800%
