Alex and Peter win some money and share it in the ratio 3:5. Alex gets £33. How much did Peter get?
IgorLugansk [536]

Answer:

Step-by-step explanation:

Set it up as fractions, Alex over Peter.

3/5 : 33/x  Let x represent Peter's amount.  Now find out: how do you get from 3 to 33?  What times 3 equals 33?  11

What you do on the top, you must do on the bottom.  If 3 times 11 equals 33, then 5 times 11 equals x.  5 times 11 equals 55, so x equals 55.

Peter will get 55.  Don't forget the pound symbol.
