Fractions, Decimals and Percentages
What is a fraction?
The pizza is one whole, each slice
is a fraction of the whole pizza.
When looking at a fraction, the line that separates the numerator and denominator can be replaced by the words 'out of'.
The fraction that represents the amount of pizza that Marie has eaten is 2/8
Use a calculator
Converting percentages to decimals:
10% = 0.10
25% = 0.25
50% = 0.50
What patterns do you see?
Converting percentages to decimals
Use your patterns to predict the decimal forms of these percentages:
75%, 20%, 33%
Did you see the pattern?
To convert a percentage to a decimal you just need to move the decimal, two places to the left.
For further information on fractions, decimals and percentages, please refer to your Revision Workbook
Marie has eaten 2 out of a possible 8 slices
Converting fractions into percentages
First, write down the fraction that you want to convert.
For example: 2/8
Try converting these
A) 1/4

B) 1/10

C) 3/5

D) 2/3
A = 1/4 = 25%
B = 1/10 = 10%
C = 3/5 = 60%
D = 2/3 = 66%
If Marie eats 2 slices of pizza, what fraction of the pizza did she eat?
Start with 100 and divide it by the denominator.
100 divided by 8 = 12.5

Multiply your answer by the numerator.
12.5 multiplied by 2 = 25

Your fraction has now been converted into a percentage.
2/8 converted to a percentage = 25%
75% = 0.75
20% = 0.20
33% = 0.33
