Problem:
Given 5.2 liters of oil weighs 3.952 kg. Find the volume of oil if it weighs 5.32 kg?
Solution method:
- Step 1: Calculate the weight of 1 liter of petroleum oil by dividing the weight of 5.2 liters of oil by 5.2
- Step 2: Find the number of liters of oil when their weight is 5.32 kg, by dividing 5.32 kg by the weight of 1 liter of petroleum oil.
Answer:
1 liter of petroleum oil weighs:
