Description

Inside Maths builds on the success of the series Maths 4 Real.Fran has a dinner party which she wants Dave to prepare. When he heads off to start cooking she explains the concept of ratios and proportions using vivid animated graphics. On arriving at Fran's flat, Dave finds out that the recipe for chilli is for four people and not the six guests that are expected. This means he has some maths to do to make sure that when he uses more ingredients, he keeps them all in the right proportion.Back in the studio Fran does that maths, creating a new ingredient list for the chilli. She then looks at the fruit punch, made from four different juices, and works out how much of each juice is required to make two litres. At the flat Dave has encountered another problem. He's been nibbling his way through a bar of chocolate and now there's not enough to make the fudge brownies. Can he, with what little chocolate is left, use ratios and proportions to make sure the brownies still taste good?
