Julia is an artist. She has been painting a huge mural for the town centre. For the main colour she used a 20 litre pail of white mixed with a 10 litre pail of blue. Unfortunately she ran out of paint before she finished the mural. She thinks that she will only need 6 more litres in total to finish. How much blue and white paint does she need to mix up to get the 6 litres of paint she needs that is exactly the same colour she has been using?

20L of white and 10L of blue paint.

20 + 10 = 30

6 divided by 30 = 5

4 x 5 = 20 and 2 x 5 = 10

4 + 2 = 6

4L of white and 2L of blue paint.
