Programme 8: The Whole Class Should be Expelled
Understanding percentages and the equivalence between percentages, fractions and decimals

Sad Man has a percentage cake with 100 bits. Mr Girhalf wants a half, that's 50 bits, Snorter wants a quarter, 25 bits and Great Big Hen wants ten bits but, before they get their percentage. Decimole appears and swallows the whole cake or one hundred per cent. Bad Man illustrates different percentages on a zany Maths Raid. In the Great Hall contestants have to answer questions against the clock and are too slow so miss their Maths Card.
