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