To get from 1 to 12 you have to times it by 12
So you do 0.19 x 12 = 2.28
Answer: The required ratio would be 
Step-by-step explanation:
Since we have given that
∠O=90°,
MO = 15, (Perpendicular)
ON = 8, (Base) and
NM = 17 (Hypotenuse)
So, we need to find the cosine of ∠N.
As we know that

Hence, the required ratio would be
