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

Answer:

13.5 glasses of water

Step-by-step 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::

$\dfrac{2/9}{1}=\dfrac{3}{x} \\\dfrac{2}{9}x=3\\ Divide both sides by \dfrac{2}{9}\\x=3 \div \dfrac{2}{9}\\x=3 \times \dfrac{9}{2}\\\\x=13.5$

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