Answer:
The proportion is 21.60 out of 30.
Step-by-step explanation:
Given:
Test worth 30 points, test score 72%.
Now, to find the proportion.
Let the test score be [tex]x.[/tex]
Test worth points is 30.
So, [tex]x[/tex] is equivalent to 30.
Percent of test score = 72% = [tex]\frac{72}{100}[/tex]
Thus, we set proportion:
[tex]\frac{x}{30} =\frac{72}{100}[/tex]
By cross multiplying we get:
[tex]100x=2160[/tex]
Dividing both sides by 100 we get:
[tex]x=21.60.[/tex]
Therefore, the proportion is 21.60 out of 30.
