For example: Convert 13% to a fraction.

*Remove the Percent sign (e.g. 13)
*Make a fraction with the percent as the numerator and 100 as the denominator (e.g. 13/100)

Changing a % to a fraction

RULE:- You simply turn it into a fraction by writing it over 100.
Then cancel down if possible.
Example:- What is 35% as a fraction?




cancelling down to the simplest form by dividing the top and bottom by 5.
*** Remember that the value of a fraction remains unchanged when you multiply or divide both the top and the bottom by the same number. ***

Changing a decimal to a %
Dead easy, this one!
Suppose we want to write 0.27 as a %. Since a decimal is a kind of fraction, all we have to do is to multiply by 100. You just need to remember that each time you multiply by 10 the number becomes larger by a factor of 10 so the decimal point moves one place to the right. Multiplying by 100 moves it 2 places to the right. This neat rule is because decimals are fractions in our base ten number system.
So we find that 0.27 is the same as (0.27 x 100)% = 27%.

Similarly, 0.735 is the same as (0.735 x 100)% = 73.5%
and 7.46 is the same as (7.46 x 100)% = 746%.


RULE:- To change a decimal to a % we multiply by 100
which just moves the decimal point 2 places to the right.
Changing a % to a decimal
(Again, dead easy!)


RULE:- All we have to do is to divide by 100, so move the decimal point 2 places
to the left.
Here are 3 examples to show you how to deal with all possible snags.
Example (1) What is 37% as a decimal?


Answer:- 37% is the same as 0.37.
Example (2) What is 25.5% as a decimal?


Answer:- 25.5% is the same as 0.255.
(Notice that the percentage had a decimal point in here too.)
Example (3) What is 50% as a decimal?


Answer:- 50% is the same as 0.50 = 0.5.
(The last zero just tells us that there is nothing in the 2nd position after the decimal point, so we can leave it out.)



Percentage increases and decreases
The easiest way to explain how to work these out is to look at some examples.
Example (1) Suppose the profits of a certain company go from £365 000 in January to £425 000 in February. What is the % increase in their profits?


RULE:- Percentage increases and decreases are always calculated with respect to the
value before the change took place.
Here, the actual increase in profits is £425 000 - £365 000 = £60 000.
The % profit is £60 000 as a percentage of £365 000




--------------------------------------------------------------------------------
Example (2) The number of first year students at a certain university studying Law was 127 in 1996 and 114 in 1997. What was the % decrease?
The actual decrease is 127 - 114 = 13.
The % decrease is 13 as a % of 127.
13 as a fraction of 127 is 13/127.
Now, just multiply by 100 so you get




--------------------------------------------------------------------------------
Example (3) The price of a certain model of car goes up by 8%. It used to cost £7 800. What will it cost in future?
There are two ways of finding this.
Method (1)
First find the actual increase in cost. This is 8% of £7 800 so it is




Therefore the new price is £7 800 + £624 = £8 424.
Method (2)
This is the all-in-one way of doing it.
The new price is 108% of the old one, so it is

Hope it help's
I dont understand a word of it
;-)
