FRACTIONS DECIMALS AND PERCENTAGES

be out of any numbers

FractionsFractions are parts of a whole and are represented like this: ½ ¾ The number on the bottom is called ‘Denominator’. It tells you how many parts a whole is divided into. Fractions are also used for discount sales. ½ price means that the price is now half the normal one. The number on the top is called ‘Numerator’. It tells you how many parts you have from the denominator. ¾ means 3 parts took from something divided into 4.

PercentagesPercentages are fractions out of 100. However, they are shown differently. This is how percentages are written: 50%, 40%. Percentages are mainly used in discount sales. If it’s 50% off, it means if the sale item was $100, the price will be $50 less.
