# Thread: coffee urn holder problem

1. ## coffee urn holder problem

A coffee urn holds 12 litres when full. Harry fills coffee cups from the urn until the coffee runs out.
(a) How many 140ml cups of coffee can be filled from the urn?
(b) At the end there is not enough coffee left to fill a cup. Harry decides to drink it himself. How much coffee is there left for him?

i did 140ml divided by 12000 = 85.7 85 cups can be used
for (b) there would be a partially filled cup for him to drink from is that correct
