25% less than 80 means 75% of 80.
That will be 75 X 80 / 100 = 60
Alternatively 25 X 80 / 100 = 20
So, 20 less than 80 means 60

80 x .25 = 20
80 - 20 = 60
or to find 25% of any number, just divide that number by 4. Think of 25% as $.25. There are 4 quarters to a dollar.
so.
25% of 80 = 20
50% of 80 = 40
75% of 80 = 60
100% of 80 = 80

Wendy, I suggest you get some paper, a pencil, and even a calculator! You could have found the answers by now without relying on everyone else doing your homework. How many homework questions do you have posted on here? You parents should be ashamed. I am ashamed for them.
