3 Look at the shaded part in these shapes: and Fractions are called A fraction is part of a whole.

4 +++++== 1 Each part is called one sixth. If we cut the tart into 6 equal parts, this is what we get.

5 This pie is divided into 6 equal parts. If we cut off The remaining part is:

6 This pie is divided into 8 equal parts. If we cut off The remaining part is:

7 A Fraction is made up of 2 numbers The top number is called the numerator The bottom number is called the denominator

8 What fraction of this shape is shaded? denominator Tells us in how many parts the shape is divided. numerator Tells us how many parts are shaded

9 What fraction of each shape is shaded? A= B = C= D=

10 of the circles are blue. What fraction of the circles are blue?

11 What fraction of each of these shapes is red? Look at these shapes What fraction of each of these shapes is blue?

12 Look closely at the shaded parts: Although divided into different parts, the same area is shaded. If we multiply the numerator and the denominator by the same number we get Equivalant Fractions

13

14 Are these equivalent fractions ? x ? ?

15 Find equivalent fractions to 1 Whole = = ==

16 When fractions have a common denominator it is easier to : compare them Which is the biggest fraction? x5 = or

17 When fractions have a common denominator it is easier to : add them x5 = + We need to find equivalent fractions with a common denominator. The Least Common Multiple of 4 and 5 is 20. x4 = = +

18 When fractions have a common denominator it is easier to : subtract them x2 = - x5 = = - We need to find equivalent fractions with a common denominator. The Least Common Multiple of 5 and 2 is 10.

19 Look closely at the shaded parts: Although divided into different parts, the same area is shaded. If we divide the numerator and the denominator by the same number we also get Equivalant Fractions 4 4 = is a fraction in its lowest terms

20 Let us reduce to its lowest terms: Factors of 8 Factors of 6 = is a fraction in its lowest terms

21 When the numerator is less than the denominator examplesexamples The fraction is called an Proper Fraction It is always less than the whole.

22 When the numerator is greater than the denominator exampleexample The fraction is called an Improper Fraction It is always more than the whole.

23 Improper Fractions can be changed into Mixed Numbers r 1 = 2= 2

24 Let`s play some

25 What fraction of the people have….. purple trousers ?Red jumpers ?blue trousers ?blonde hair ?black hair ?

26 What fraction of the Fripples is …. spotted

27 What fraction of the Fripples is …. striped
