- 1) Total points = 25
- 2) Points earned = 21
- 3) Percent score = 84%
Proportion:
Solving the others in the table
21 out of 25 points:
- 21/25 = x/ 100 ⇒ x = 100*21/25 = 84
15 out of 20 points:
- 15/20 = x/100 ⇒ x = 100*15/20 = 75
47 out of 50 points:
- 47/50 = x/100 ⇒ x = 100*47/50 = 94
28 out of 30 points:
- 20 / 30 = x/100 ⇒ x = 100*20/30 = 66.66
19 out of 45 points:
- 19/45 = x/100 ⇒ x = 100*19/45 = 42.22
3 out of 4 points:
- 3/4 = x/100 ⇒ x = 100*3/4 = 75
