Answer:
3( 73/84 )left over
Step-by-step explanation:
She had 6 gallons in total 
2/3+1/4+1/2+5/7=179/84   =  2 ( 11/84)
6/1-179/84 = 325/84    =  3(73/84)
She used  179/84
She have left 325/84
179/84   +  325/84 = 6
    With mixed numbers:
2  11/84   
3  73/84
  2+3=5                11/84+73/84= 84/84 =1
5+1=6
  
 
        
             
        
        
        
Answer:
-1/2
Step-by-step explanation:
it has to be a negative number since
every other number is negative
its a fraction since the numbers are decreasing
96 divided by 48 is 2
so the number being multiplied or ration must be -1/2
 
        
             
        
        
        
8,000 x .80= 6,400
8,000-6,400= 1,600
1,600-1,000= 600 that is the amount of tuition she will need to pay each year.
