Hopefully you already know how to change a fraction to a decimal.
For instance ²⁄³ =2 ÷ 3= 0.6666… This is a recurring decimal. But changing a recurring decimal back to a fraction is a little more complicated.
UK maths teacher have produced a great video on this.
If you prefer a written explanation Study maths have produced a good introduction of how to convert a recurring decimal to a fraction.

There is also an interactive worksheet to make sure you can do it.

You can find it on Google Play. I am recommending this because it is good, not because I have any connection to the app.

You need to find the lowest common multiple when finding common denominators to add fractions. Highest common factors are also used in fraction or ratio calculations when you cancel down. This interactive worksheet will show you how to work them out.

Why does the bank always win? Probability shows us that the odds are stacked against the gambler.
Let me explain. Say we place a bet of £1 on Number 24. Assuming the roulette wheel is fair, there is one chance in 37 of this happening, because there are 37 different numbers on the roulette wheel. If you win, the bank pays you 35 times your bet. So if we do this 37 times we would expect to win once. We would lose £37 in bets and win back £36, so overall we lose £1!
A similar thing happens if you bet on pair (even) or impair (odd). Zero does not count as odd or even. So the probability of getting an even number is 18/37. The probability of an odd number is also 18/37. If you win the bank pays you the same amount as your bet. So if we play 37 times, each time betting £1, we would only expect to win 18 times. We would bet £37 and win £18 x 2 =£36, losing £1 overall.
Casinos make massive profits as they are always bound to win in the long run. True, very occasionally someone strikes lucky and has a big win, but the casino knows the odds are stacked in their favour.

Equivalent means equal to. So in this matching game you just have to match the pairs of equal fractions, eg ½ = 2/4 , or 3/9 = 1/3

You need to understand there are four suits, spades♠, hearts♥, diamonds♦ and clubs♣.
Spades and clubs are black, hearts and diamonds are red. There are 13 cards in each suit, so altogether there are 4×13=52 cards in a pack. Number one is called an Ace. They are then numbered up to 10. After 10 there is a Jack, Queen and King.These are called picture cards.
Thanks to Mr Barton Maths for this Jigsaw.

Finding half of a number is the same as dividing by 2. So half of 16 is 8.

See how much money you can win on this addictive game! To calculate the probability each time work out first how many card are left and put this number on the bottom of the fraction. Then work out how many cards that haven’t been turned over yet are higher or lower than the last card. Put this number on the top.Sometimes you will be certain that the next card is higher or lower because all the cards that are higher have already been turned over. If you are certain then it is worth wagering all the money. If the probability is nearer to a half only gamble a small amount of money. This way you should soon become rich!
