We can see that ½ is the

same as 2/4, 3/6, 4/8 and

5/10.

These are EQUIVALENT

FRACTIONS.

Find me an equivalent of:

2/8 3/9 8/10 9/9 4/6

Simplified Fractions

To simplify a fraction, we

find an equivalent fraction

which uses the smallest

numbers possible.

We do this by

dividing.

We need to know our

tables for this!

Ask yourself, what can I

divide both 24 and 40 by?

8 is the biggest number

we can divide both by and

3/5 uses the smallest

possible numbers as we

cannot divide them by

anything else.

Look at this one

28

56

The first thing I notice is

that 28 and 56 are both in

the 7 times table. So I’m

going to divide both

numbers by 7.

STEPS TO SUCCESS

• convert – to change from one form to another

• mixed number – a whole number and a fraction

• improper fraction – a fraction larger than one whole; the numerator is larger than the denominator

IMPROPER FRACTIONS

• A fraction in which the numerator is greater than the denominator.

They are BIG HEADED!!

MIXED NUMBERS

• A mixed number has a part that is a whole and a part that is a fraction.

They’re a bit mixed up!

2. Add your answer to the numerator

3. Put that number on top of the denominator

Get out into your gardens or on your daily walk

and collect some leaves or petals. Use crayons,

pencils of even paint to create your own either

rubbed or printed images of leaves in bright

colours – email your images in and I shall print

them off to send up to the care home in order to

brighten up the residents days! Maybe you could

write a nice message for them to see too!
