Watch: Multiplying fractions
To multiply fractions, you need to multiply the numerators together and multiply the denominators together.
Ooooh, a raffle!
Ha, you probably have more chances of being hit by lightning than you do of winning that bike.
You bought a quarter of the tickets?
And then you bought a third of the tickets off her?
So what fraction of all of the tickets do you have?
She bought a quarter of the tickets and you bought a third of those.
So you multiply the two numerators together and then multiply the 2 denominators together.
So you have one twelfth of all the tickets.
Whereas you had a quarter of the tickets, but you sold 1 third of them so you have 2 thirds of a quarter of the tickets left, that's 2 twelfths.
Well, what are the chances!
