mandy jane · 2013-11-01 07:40:53

hi steve b mandy here sorry it is a bit later then i said? can you send me a mixture of question to do please? hope you are ok?

SteveB · 2013-11-01 07:42:15

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

mandy jane · 2013-11-01 07:42:44

hi steve b send me the question and i will have them done for you tomorrow ok?

SteveB · 2013-11-01 07:43:16

That was one to try I can make up a few more a bit later and send them by email.

mandy jane · 2013-11-01 07:46:29

hi steve is the answer(c) 200 am i right

SteveB · 2013-11-01 07:47:45

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

hi steve b can you should me what to do then?

SteveB · 2013-11-01 07:50:55

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

SteveB · 2013-11-01 07:52:50

Notice that Karen gets £160, and that £160 + £240 = £400
This is a useful checking method for ratio questions.

mandy jane · 2013-11-01 07:53:16

ok do you have aother that i can try please?

SteveB · 2013-11-01 07:54:27

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.

mandy jane · 2013-11-01 07:57:31

400 / 4 = 100

300 x 1 = 300
am i right or not

SteveB · 2013-11-01 07:58:23

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 ?

mandy jane · 2013-11-01 08:02:41

210 / 5 = 42
42 x 5 = 210 is peter
42 x 2 = 84 is john
am i right or not?

SteveB · 2013-11-01 08:04:09

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

SteveB · 2013-11-01 08:09:31

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 ?)
