Some Real Life Examples

**FRACTIONS**

DECIMALS

**Percentages**

Core

A fraction is a part of a whole

ARE ALSO PARTS OF NUMBERS .....

THE DECIMAL POINT SEPARATES THE WHOLE FROM THE PART .....

A percent or percentage is a number out of 100.

Slice a pizza and you will have a fraction.....

What is part of a whole ?

The top number tell you how many pieces you

HAVE

The bottom number tells you how many slices the pizza was

CUT INTO

but .... we don't always

work with wholes.....

What is a whole?

100% is a whole

1.00 is a whole

4 / 4 pieces is a whole

It has 2 parts :

NUMERATOR

DENOMINATOR

We call the top number the

Numerator

, it is the number of parts you have.

We call the bottom number the

Denominator

, it is the number of parts the whole is divided into.

Equivalent Fractions

Some fractions may look different, but are really the same,

for example:

* It is usually best to show an answer using the simplest fraction ( 1/2 in this case ). That is called Simplifying, or Reducing the Fraction

write down your answer in

your math book .... the answer will be revealed at the end of the lesson .

ADDING FRACTIONS

You can add fractions easily if the bottom number (the denominator) is the same:

another example:

SUBTRACTING FRACTIONS

3 simple steps to subtract fractions

Step 1.

Make sure the bottom numbers (the denominators) are the same

Step 2.

Subtract the top numbers (the numerators). Put the answer over the same denominator.

Step 3.

Simplify the fraction.

DECIMALS

The decimal point separates the whole number from parts

.1 OR .10

BOTH IMAGES ARE EQUAL TO

ONE - TENTH

WHAT DECIMAL IS REPRESENTED BY THIS MODEL ?

copy this question into your math book showing how you got your answer....

40 out or 100

= 40%

WHAT PERCENTAGE OF PLANES ARE SHADED RED?

Now it's your turn! In your math book turn this 20 cent piece into a fraction, decimal and percent....

YOUR NOW GOING TO CREATE YOUR OWN PARK!

Using the 100 grid paper provided ...your now going to become a landscape architect and create your own park ......

THE PARK MUST INCLUDE:

Playgrounds

Grass

Trees

Water

Sporting grounds

Something else (of your choice)

example of a park I made earlier .

CONCLUSION

Now you're going to calculate the fraction of each part of your park and write your answer in your math book drawing the table below:
