Liann works in the olde tyme Soda shoppe. The shop sells milkshakes, double milkshakes, and triple milkshakes. A shake uses 1/8 cup of syrup, a double shake uses 1/4 cup of syrup, and a triple shake uses 3/8 cup of syrup. How many shakes of each kind could she make with 3 cups of syrup?

Syrup required for one cup of each kind
= 1/8+1/4+3/8
= 3/4 cup
1 of each : 3/4 cup
x of each : 3 cups
Cross multiply:
x = 1*3/(3/4)
=4
Lyann can make 4 of each kind of shakes.
