Solving proportion puzzles with bar modelling

Solving proportion puzzles with bar modelling worksheet
Bar models can help us visualise a problem and work out what operation we need to use to find a missing number. The key to bar models is to label the model with the information you know and the number you are trying to find (which is normally shown with a question mark). Can you use bar models to answer these questions?
