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?

Answer 1

13.5 glasses of water

Explanation:

If:

1 water glass can hold 2/9 of a litre

x water glasses can hold 3 litres.

Therefore, expressing it as a litre to glass ratio, we have::

`(2/9)/(1)=(3)/(x) \\(2)/(9)x=3\\$Divide both sides by$ (2)/(9)\\x=3 / (2)/(9)\\x=3 * (9)/(2)\\\\x=13.5`

Therefore, 13.5 glasses of water can be filled with a 3 litre bottle.
