Step-by-step explanation:
When reducing a number to its lowest term you use the GCF of the denominator and numerator then divide using this number. :
÷
= 
The gcf of 75 and 225 is 75 so we divide both the numerator and denominator by 75.

Answer:
Option D: 0.3069
Step-by-step explanation:
Formula for coefficient of variation on the company's stock is;
CV = σ/E(r)
Where σ is the standard deviation and E(r) is expected value of return.
From the attached image, we can find E(r) as;
E(r) = 0.45(25) + 0.5(15) + 0.05(5)
E(r) = 19%
From online calculation, the standard deviation is 5.83%
Thus;
CV = 5.831/19
CV ≈ 0.3069
It’s 9.9 because 3 times 3.3 is 9.9
