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.
