#22. We are given that y = 1/4. So, we want to plug this value into the expression 15/y:

15/(1/4)

When you divide by a fraction, you should follow the rule “flip the guy and multiply”. Basically, 15/(1/4) = 15 * 4 = 60.

The answer for #22 is (D).

#23. We can use a proportion:

(The shaded area)/(entire circle area) = (360 - 60)/360

But, we don’t have to find the areas of the region and circle; we can just solve the fraction:

(360 - 60)/360 = 300/360 = 30/36 = 5/6

The answer for #23 is (A).
