Li had gallons of juice. he served gallons at breakfast.
how many gallons of juice does li have left?
gallons

Oh ok! 

Work:
So she has 5 2/3 and she served 1 3/4

First thing u need to do is make the bottem number of the freaction the same number so what u need to do is 3*4=12 

Then multiply the top nubers by the other bottem number so for 2/3 do 2*4=8
and for 3/4 do 3*3=9 

So now u have your fractions"

She had 5 8/12 and gave away 1 9/12

Now tht u ahev those mubers subtract them 
First do the fractions (the bottem number stays the same!)

So 8/12 - 9/12 = 1/12

Now thw whole numbers 5 - 2 =  3

So she has 2 11/12 left!
