example 4: The Sharmas consumed 8 L 350 mL of milk and the Vermas consumed
11 L 125 mL of milk in a week. Who consumed more and by how much?

Solution: 8 L 350 mL < 11 L 125 mL
So, the Vermas consumed more milk.

Now, L mL

10 10
0 0 12
Milk consumed by Vermas = 1 1 1 2 5
Milk consumed by Sharmas = – 8 3 5 0

Difference in consumption = 2 7 7 5

Thus, the Vermas consumed 2 L 775 mL more milk than the Sharmas.
