you know when i told you that i had trouble with percentage? well this is how i find the percentage.

1/5= 0.20. then if it's $20. i just multiply 0.20 with $20
but when my techer was giving us problems. i got it wrong three times in a row. she said that we had to add something and subtract something.so confusing.

Please post one of the problems and I'll try to explain it for you.
