Drag the amounts to order them from greatest to least.
1 qt ≈ 0.95 l
1 gal = 4 qt
1 qt = 2 pt

3. 8 pt0.6 gal1. 9 l

To be able to order the given amounts of fluid, we simply have to convert all of them to a common unit. 
   
     (a) 3.8 pt (1 qt / 2 pt) = 1.9 qt
     (b) 0.6 gal (4 qt / 1 gal) = 2.4 qt
     (c) 1.9 L (1 qt / 0.95 L) = 2 qt
Arranging them from greatest to least will give us the answer of
                              0.6 gal, 1.9 L, 3.8 pt
