A fountain holds 12,500 gallons of water. Joe wants to find how many liters that is. (1 L=0.26 gal; 1 gal= 3.79 ) Which proportion could he use to solve for the number of liters?
A. 1 L/0.26=12,500 gal/x L
B. 0.26 gal/1 L= 1 gal/12,500 L
C. 3.79 L/1 gal= 12,500 gal/x L
D. 1 gal/3.79 L= 12,500 gal/x L
gal * L/gal = L
or, as a proportion,
xL/12500gal = 3.79L/1gal
12500gal/xL = 0.26gal/1L
