It helps you because it makes it easier to divide you just have to keep using place value to find the quitent
        
             
        
        
        
1) first pick red 5/9 blue 4/9 
2) second pick when red has been picked red now becomes 4/8, blue stays 4/8
2) Second pick when blue has been picked blue now becomes 3/8, red stays 5/8
Mind you, you only need both different colours so:
first pick red 5/9 x sec pick blue 4/8 = 20/72
and first pick blue 4/9 x sec pick red 5/8 = 20/72
add both up 20/72 + 20/72 = 40/72 = 5/9
 
        
             
        
        
        
Answer:
12 in.
Step-by-step explanation:
The perimeter is calculated by adding all up the sides of a shape.  In this case, the shape is a square, considering that all the sides are the same measurements.  3+3+3+3 can be simplified to 3x4.  This gives you 12 in. as the perimeter.
