Karen and Lisa have earned £400 in total.

It is to be split into a ratio as follows:

Karen gets £2 for every £3 Lisa gets given.

That is to say a 2 : 3 ratio.

How much is Lisa paid ?

(a) 240

(b) 133

(c) 200

(d) 180

No that is not the right answer. What was your method for that ?

I was hoping for this method:

(1) First divide the total of £400 into 5 equal parts. £400 / 5 = £80

(2) Then give 3 of them to Lisa: £80 x 3 = £240

Notice that Karen gets £160, and that £160 + £240 = £400

This is a useful checking method for ratio questions.

Try splitting £400 into a 3:1 ratio

How much does each person get ?

Let us say that Gary has the 3 and Mike has the 1 in this case.

400 / 4 = 100

300 x 1 = 300

am i right or not

Yes provided you get them the right way round that is correct. In a real question you would have to give the

named people if the question asked this. In a real question the English would be clearer - I wrote that in a rush....

Another one before I forget it £210 is to be split into a 2:5 ratio.

The five parts are to go to Peter and two parts of it are to go to John.

How much does John get given ?

How much does Peter get given ?

210 / 5 = 42

42 x 5 = 210 is peter

42 x 2 = 84 is john

am i right or not?

Now look at what you have written and do this: Add together the two amounts - do they add up to £210 ?

I am getting £294 as the total: Something has gone wrong the total is higher than the total of £210

You did not divide by a high enough number.... (try again perhaps ?)
