when some one speaks of percentage, what number are they referring to?

no, a percent refers to 100

you have to give 100%

Take a dollar bill. It is 100 pennies, right?
So how much is 20%

i dont know im sorry i am not good with percents :(

if one dollar is 100 pennies, then 100% of one dollar is 100 pennies.
Do you follow that?

yes

So if you take 20% from 100% how much is left?

80

Great

Know, how do we write out one dollar?

1.00

that 1 is 100%

oooh ok i kinda understand now

if we took one penny away we would have 99 cents
0.99

So how would you write 80%

0.80

Yes, good job

So now you are ready to do the problem

ok

now you have 6 and you want to take 20% away.
So, you can multiply by 80%

ok 5.80??

Multiply 6 * 80% like you wrote it

No, not quite. You subtracted .20 cents not 20%

4.8

Yes, great job

Now do the same for the 9

multiply it by 80??

80%

7.2

yes, good job

so you now have your two new dimentions

thank you i never understood how to do percent problems thank you :)

k bye gtg thx again :)
