Question

You are decorating your bedroom. To get the paint colour you want, you mix 2 parts red with 3 parts cream and 1 part blue. How much cream and blue paint will you need to mix with 4 litres of red? 4 litres red: litres cream litres blue

Answer 1

To make 4 parts red, you need 6 parts cream and 2 parts blue.

Answer 2

If 2 parts red is equal to 4 litres of red. Then 3 parts cream is equal to 6 litres of cream and 1 part blue is equal to 2 litres of blue.

I got this by dividing 4 litres by 2 parts.

4/2 = 2. So, 2 litres is 1 part.

I then multiply 2 litres to the number of parts to get the number of litres of cream and blue

2 litres * 3 parts = 6 litres cream

2 litres * 1 part = 2 litres blue
