Not sure that the answer is one offered.
Receipe makes 12 litres of paint. Jack needs 5 litres which is slightly under half of the receipe. Therefore, he will need slightly under 1/2 litre of blue - there is no answer that small!
Or am I being totally stupid. We were always taught to roughly estimate the answer before working out so we knew if we were completely off track or not.
