Question

9. A water glass can hold 2/9 of a litre of water. How many glasses of water can be filled with a 3 litre bottle?

Solve the problem

Answer 1

13 1/2 glasses of water.

Explanation:

From the question, a water glass can hold 2/9 of a litre of water, to know the number of glasses of water that can be filled with a 3-litres bottle, the following steps are crucial;

1 water of glass = 2/9 litre of water

x = 3 litre of water

cross multiplying;

2/9 * x = 3*1

2x/9 = 3

2x = 27

Dividing both sides by 2;

2x/2 = 27/2

x = 13 1/2

This means 13 1/2 glasses of water can be filled with a 3-litre bottle.
