Maths Strategy Week 6 Term 4 4

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?


For every 20 litres of white paint, she needs 10 litres of Blue Paint. 20:10

She needs 6 more litres of white paint so then we need 3 litres of blue. 6:3
