Hi... I am Fractionstein. Did you know that fractions are not as scary as you might think? Learn along with me and you will be an expert at fractions in no time at all!
What are fractions? Fractions are parts of whole things. We use fractions every day! Zack played really well in the first half of the match! The time is quarter past twelve. Mia is ½ years old. Somebody has already eaten three-quarters of this pizza! Images: ThinkStock
We write fractions using a numerator and a denominator. The numerator tells us how many parts we have. The denominator tells us how many parts something was (or is) divided into. There are three pieces left. There were four pieces. There are five green buttons. There are eight buttons altogether. The There is one piece of cake left. cake was cut into six pieces.

There are lots of different types of fractions. Here are some of them... Halves Thirds What fraction of my flag is coloured pink? Quarters Fifths What do you notice about the size of the pieces in each fraction? Eighths Tenths 0
If the denominators are the same, adding and subtracting fractions is easy. Did you know that we can add and subtract fractions? If the denominators are different, we have to change the fractions so that they have a common denominator. + 0 + + 0? 0 - - -?
It is helpful if you can remember these fractions, decimals and percentages! Fraction Decimal Percentage 00% / 0. % / 0..% / 0. 0% / 0..% / 0. % / 0. 0% / 0..% /0 0. 0% /00 0.0 %
fraction numerator denominator common denominator Fractions are parts of whole things. cancel simplify decimal decimal point Cancelling fractions is when we divide the numerator and denominator by the same number. 0 00 0 0 0 This is the top number in a fraction. It tells us how many parts we have. Simplifying fractions means finding an equivalent fraction where the numerator and denominator are as small as they can be. This is the bottom number in a fraction. It tells us how many parts something was (or is) divided into. Decimal numbers contain a decimal point. They might also include tenths, hundredths and other numbers smaller than one. 0. Different fractions that all have the same denominator. This makes it easier to order, add and subtract them. A decimal point separates the whole numbers from the numbers that are smaller than one..0.0.
