we are given 
The scale is 

the distance from Happy Hill Park to Rainbow Valley Park is 4 1/2 inches
we can change it into rational form
and we get 

so, we can multiply both sides by 9 

now, we can simplify it 

so, the actual distance between the two parks is 27 miles........Answer
 
        
             
        
        
        
Answer:
37.5
Step-by-step explanation:
so x% of 40 is 15
the equation for that is 
x/100 * 40 = 15
40x/100 = 15
multiply 100 on both sides
40x = 1500
divide 40 on both sides
37.5
37.5% of 40 is 15
 
        
                    
             
        
        
        
Answer:
4 1/2
Step-by-step explanation:
Look at this expression as given in the original problem; the numbers, properly typewritten, are    -5  1/2,  - 4  1/4,  + 6  3/4.
We want to combine these three numbers into one.
To do this, we need the LCD; it is 4.
Thus, -5  1/2 is rewritten as  -5  2/4.
Then we have 
-5  2/4 - 4  1/4 + 6  3/4  = -5 -4 + 6 + 2/4 + 1/4 + 3/4.
This simplifies to:                 +3 + 6/4, or 3 + 1  + 2/4, or
                                                                       4  1/2
 
        
             
        
        
        
Answer:
