    My maths tutor has recommended to watch two videos explaining probability (I was never taught them at school) one of them being BBC Bitesize. I have watched them and a couple of others but this is by far the best explanation I have come across. I will find more videos by Ron Barrow to teach me maths, hoping they are as easy to understand as this one.

    When you multiply two fractions that are tenths, the answer has a denominator of 10x10 = 100. If you multiply 3/10 by 7/10 you get 21/100. If you don't get that then look again at how to multiply fractions.
