to make an environmentally safe furniture polish, you can combine lemon oil and mineral oil in the ratio 3:200, by volume. How much lemon oil do you need to make 10.15L of polish?

Hi Sajad,

The instructions say to take 3 units of lemon oil and 200 units of vegetable oil and mix them. This gives a volume of 203 units of the polish and the fraction of this that is lemon oil is 3/203. Thus 3/203 is the fraction of the 10.15L of polish that is lemon oil.
