Answer:
13 1/2 glasses of water.
Step-by-step 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.
