Step-by-step explanation:
It is given that, three oil tankers together contain 37 5/7 litres of oil.
Total volume of oil is 
If two tankers have 11 3/14 litres and 12 3/7 litres of oil.
Oil in first tanker is 
Oil in second tanker is 
Oil in first and second tanker is :

Noo, oil in the third tanker = total volume - (Oil in first tanker + second tanker )

Hence, this is the required solution.
