Question

Five litres of paint cost R575 work out the cost of fifteen litres of paint

Answer 1

It will cost R1725

The ratio for this problem is 5: 575.

(litres of paint: price)

We first need to figure out how to go from 5 to 15.

• 5 × 3 = 15

To go from 5 to 15, we multiply the 5 by 3.

Now that we have this, we need to multiply the other side of the ratio (575) by 3.

• 575 × 3 = 1725

The ratio now looks like this:

15: 1725

Therefore, for every fifteen litres of paint, it will cost R1725.
