You know what Billie has, rearrange the equation I gave to find Chris. Sorry just don't want to hand over the entire thing.

Billie has 8. 8 = 2/3 x chris. Divide 8 by 2/3 so Chris is the subject.

So is it 1.3 reoccurring?

No it's 12. Dividing by 2/3 is the same as multiplying by 3/2.

Oh yes sorry, is that it?

Is that the answer or do I do 12x4/5 ?

12 = 4/5 x age. So it's the same procedure as the last step.

Ok so that is 9.60 is that the amount of money he has right?

No it should become larger. It's 12 divided by 4/5 which is multiplying by 5/4.

Thanks so much, how do you know what to do in these type of questions?

Try and convert the words into mathematical equations, assign variables, form equations, etc...

Moving this to maths btw.

I create equations from what information the question gives. I then rearrange the equations to find each thing that I need to get to the answer. e.g with Billie = 2/3 x chris and I need to find Chris I multiply both sides by 3/2.
