divide by 4, then multiply your new number by three
You take the original value times 0.25. That number is 25% of the original, so you take the original number minus that number.
The quickest way is to multiply the original number by 0.9
work out 10% and then half it, add the two together and take it away from the first number
5 percent i got it off of the worlds best math book so trust me
thirty percent of 100 is 30..it's because a percent is out of 100..i hope that helps and dont fail your math test!!!
It will take $12.80 off so they will be $25.20. :P MATH

Take your number and multiply by .85
Take a number and multiply it by .75
divide by 4, then multiply your new number by three
36.00
You take the original value times 0.25. That number is 25% of the original, so you take the original number minus that number.
16% of 5 = 0.8
The quickest way is to multiply the original number by 0.9
This is how i do it! Take the percent and place it over 100 (100 is supposed to be the denominator!) Then you take the percent sign off of the percent number (2) and simplify to its lowest terms! Then you should have 1/50.
Oh, dude, math time! So, if 20 is 50% of a number, that means the number is double 20, which is 40. It's like when you buy one, get one free - except in this case, you only get half off. Math can be fun, right?
