You need to find a common factor that both the 
numerator 
and denominator have. 16 and 12 have common divisible factors of 2 and 4(excluding 1, because 1 is self-defined but doesn't simplify values at all). 
We use the highest factor, in this case, 4. 
Divide 16 by 4 and 12 by 4.
16/4 = 4
12/4 = 3
We put 4 in place of the numerator and 3 in place of the denominator.

Answer: 7.85
Explanation: The formula you would use to find the area for the shaded sector is 
degree / 360 • 3.14 • r^2 
36 / 360 • 3.14 • 5^2 
You would square it because we’re looking for area.
