to understand percntage problems...

in order to solve percentage problems you have to understand what is the word percent or percentage means.

actually its an abreviation of "every cent" or commonly we heard as "per cent".

"every cent" means "every 100"

that is why when you say 1 percent it is equal to "1 in every 100"

15 percent = 15 in every 100 = 15/100

31 percent = 31 in every 100 = 31/100

120 percent = 120 in every 100 = 120/100

so on and so forth.

just remember when you encounter the word percent, bear in mind always that its a ratio of the number to a hundred.

very basic:

X percent = x divide by 100

or x% = x/100

hope you can handle all your percent problems after reading this.

1.5% of 157,500 is what?

1.5% X 157,500 = ?

{ When you are finding a percent of a number, it's multiplication. }

.015 X 157,500 = 2,362.5

{ Convert the % to a decimaland multiply! }

100 % of 157,500 is the actual value: 157,500

to find 1% divide that answer by 100 to get 1,575

you need 1.5%

1% = 1,575

0.5% = 1,575 / 2 = 782.5

1.5% = 1575 + 782.5 = 2357.5

2362.5

the only way I can do a % without a calculator is : is over of equals % over 100, then you cross multiply and divide. So your "is" x over 157,500. and 1.5% over 100. 100x = 236250. divide by 100, x= 2362.5. I know that is a long way, but easy to remember.

is/of = %/100

one and half percent ofd 157,500=3/200 x 157,500=2362.5

(157,500) (1 1/2 %) /(100%)

= (157,500) (3/2 %) /(100%)

= 2362.5

As a general rule you should tip a certain percentage of the bill (i usually do 12-15%)...but this also depends on the service(if it was good or bad)....I also usually tip more if the waiter is younger(I assume they are in school and probally need it)..but no some people(not just Blacks) do not know they should tip a percentage of the bill....they just always tip a standard dollar amount.

In order to find X percent of a number, multiply the number by X and divide by 100.

1.5% as a decimal is .015. You just move the decimal point two places to the left to get this, filling in with 0's if needed. That is the same as dividing by 100.

You get your answer by multiplying 157500 by .015, which you can do on a calculator as well as anyone.

(1.5/100)(157,500)
