My strategy Week 6 Term 4 part four

4.  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? answer: 4 litres of pail white, 2 litres of pail blue. (4:2)

20:10 is the ratios so far but to get to 6 litres I
dived each side by 10. So the ratios will be 2:1.

Then I times each side by 2. So the ratios will be 
4 : 2. Which is also equal to 6 litres.
