Hi all.

Can anyone shed some light on the best way to tackle the following 3 questions that crop up in Nfer papers. The first (‘scale type’) question is a particular pain.

1. A map of Ireland is drawn to a scale of 1:325,000. How many cm on the map would show 65km?


2. A water tank has a volume of 1 cubic metre. Find (a) its volume in cm cubed b) the mass of the water in kg.


Is the best/quickest way to tackle the following ‘best buy’ question to calculate 1kg first?

3. Which is the better buy per kg and by how much?

Y a-5kg pack costing 75p
Z a 1250-g pack costing 20p.

Many thanks!
