Fractions: Making sense
1.
2. Look at the shaded part in these shapes:
A fraction is part of a whole.
1 3 2 3
2 4 3 8
1 3 2 and 3 are called
2 4 3 8
Fractions
3. If we cut the tart into 6 equal parts, this is what we get.
Each part is called one sixth.

6. A Fraction is made up of 2 numbers
The top number
is called the 3 numerator
8
The bottom number
is called the denominator
7. What fraction of this shape is shaded?
3
4
1 2
3
1
2
numerator 3
Tells us how
many parts
are shaded. 4 denominator
Tells us in how many
parts the shape is divided.
8. What fraction of each shape is shaded?

D= 8
9. What fraction of the circles are blue?
1 of the circles are blue.

10. Look at these shapes
1 1 1 3 1 1
2 2 8 8 2 4
What fraction of each of these shapes is
What fraction of each of these shapes is
blue?
red?
11. Although divided the shaded parts:
Look closely at into different parts,
Equivalant Fractions
the same area is shaded.
If we multiply the numerator and the
denominator by the same number
we get
15. When fractions have a common denominator it is
easier to :
compare them
Which is the biggest fraction?
17 3
o
20 r 4
3 15
x5
x5 =
4 20
16. When fractions have a common denominator it is
easier to :
add them
3 12
x4
1= 5
x5
=
1 3 5 x4 20
4x5 20 +
4 5
We need to find equivalent fractions with a common
enominator. The Least Common Multiple of 4 and 5 is 20.
5 + 12 17
=
20 20 20
17. When fractions have a common denominator it is
easier to :
subtract them

We need to find equivalent fractions with a common
