I could help. So mark days as the X value and hours as the Y value
so for the days(x) start with 1 and put in the hours(y) 24 the for the second column in the days(x) box put 2 and in the hours(y) put 48 then continue to at 12 to the hours(y) and 1 to the days(x)
        
             
        
        
        
Take the first 2 and take out -7x2. bringing it to (-7x2)(x-3)+(3x-9)
then take out 3 on the right side. 
-7x^2 (x-3)+3 (x-3)
factors to (3-7x2)(x-3)
        
                    
             
        
        
        
In order for us to tell whichever fraction is greater than or lesser than, we need to look for the missing part. 
For example,  we have 2/3 and 1/3.
2/3 needs to have 1/3 in order to complete the whole.
1/3 needs to have 2/3 in order to complete the whole.
1/3 < 2/3
<span>So 2/3 is bigger than 1//3</span>
        
             
        
        
        
<u>What we know</u>:
- Bird feeder capacity:             -->  2 4/5 cups
- Samantha's scoop capacity: -->  7/10 cups
<em>Lets first convert the mixed partial fraction --> improper fraction</em>
<em>        --> for easier calculation</em>
<em />
<u>After Conversion:</u>
- Bird feeder capacity:             -->  14/5 cups
- Samantha's scoop capacity: -->  7/10 cups
<u>To find how many scoops of birdseed will Samantha put into the feeder we must:</u>
   --> divide the total capacity by the scoop's capacity
        --> find the number of scoops:
<u>Solve:</u>
   
Thus the total number of scoops that Samantha will put into the bird feeder is <u>4</u>
<u></u>
<u>Answer: 4</u>

Hope that helps!
