Paul, Fiona and Pip share some sweets in the ratio 4 to 5 to 1. Paul gets 15 more sweets than Pip. How many sweets does Fiona get?
You can interpret the ratio as poor pip only getting 1 sweet for Paul's 4. So let's call Paul's sweets x, Pip's sweets y.
Using this info and the info in the question, can you set up two simultaneous equations?

Hey,
U can solve the problem in the following way easily.
step 1: write everything in terms of a variable. so lets assume Pip got X sweets.
Step 2: Rewrite the ratios in terms of variables. So the ratio becomes
4X : 5X : X
Step 3: So, now we can get an equation to find X. We also know that the ratio of Paul got 15 more than pip.
SO,
(X+15) = 4X.
solving this we get X= 20.
So since Fiona got 5X she has got 25 sweets.
