 - a PERCENT is a fraction that is out of a 100.

 - It is part of a whole.

 - It can be converted into a ratio.

   - a ratio shows the relationship between part to part that when added gives you part to whole

 - It can be converted in a fraction.

   - a fraction is a number less than one; the numerator is the part; the denominator is the whole

 - It can also be converted into a decimal.

   - a percent is a number that represents as a part of a whole number using tenths, hundredths...

 

here is a website that shows more information about percents..

this is a grid.  [ 96 out of a hundred = 96 % ]

 

this picture that shows 50 % = half

this is not a joke ! 

 

 

You may be thinking, "how will percents help us in life?"

WELL, we've got the answer.

what if you were asked a percentage question that if you got wrong, you would die.

or what if you came across a car sale and the cars were 50% off.

if you don't know about percents, you'd have to pay $12 000 for a car instead of $6000, (which is WAAAAAAAAAAAAY cheaper).

 

if you would like to learn about percents, answer some of these questions:

20 is 70% of what number?

- to get the answer, you would:

A) REWRITE:

- 20 = 70% of ____.

B) DIVIDE:

- 20/70 = 0.285

C) MULTIPLY:

- 0.285 x 100 = 28.5

D) REWRITE SOLUTION:

- 20 = 70% of 28.5

 

TO CHECK TO SEE IF IT IS RIGHT...

turn the percent into a fraction 70/100. Then into a decimal = 0.7

and check to see if it is equal to 20/28.5 by turning it into a decimal = 0.7

 

TIP: When you rewrite: "of" is 'multiply'

                                       "is" is 'equals'

 

 

NOW TRY SOME FOR YOURSELF:

 

1.) What is 87% of 420?

2.) what percent of 65 is 50?

3.)75% of what number is 40?

 

HIGHLIGHT FOR ANSWERS:

1) 365.4

2) 76.9

3) 53.3
