Weekly Maths Problem

Don’t forget to write out the problem at the top of the page, date the work and show all your workings out (even the wrong answers) and then file the evidence in your folder!

I am about to decorate my small Christmas tree, the one I put on the kitchen window. In the box of decorations, there are a number of small bubbles I can use. All of them are blue, except for six. All of them are green except for six. All of them are red, except for six. How many bubbles do I have in total and in what ratio are the blue: green: red babbles?

You can share your answers here in the forum on the website or with me as I visit during the week. Remember you need to show your workings out to get the maximum points.
