Find the greatest common factor and then divide each number by it. 
in this case the gcf for 75 and 100 is 25.
75 divided by 25 = 3
100 divided by 25 = 4
so 75/100 simplified = 3/4
        
                    
             
        
        
        
There are 8 yellow and 24 blue. Our ratio from yellow to blue is 8:24.
To simplify this, we need to see if we can divide 8 and 24 by a common factor.
8 and 24 can be divided by 8, so let's do that.
8/8 = 1.
24/8 = 3.
Your new and simplified ratio is 1:3 from yellow to blue, but we're looking for blue to yellow. Flip the ratio.
3:1 is your ratio.
C.) is your correct answer.
I hope this helps!

Answer:
x = 9
Step-by-step explanation:
We are going to isolate x
14 - x = 5
subtract 14 from 5
-x = -9
multiply both sides by -1 to make x positive
x = 9
