X=20+20/100
X=2020/100=20.2

So 20 must = 80% of something
therefore 1% must be 20/ 80 which is 1/4
THEN 100 times this 25
So could x = 25
I think it is!

Hmmmm.....O.o....I don't know....O.o....Sorry...:S

Check by finding 20% of 25 and subtracting it from 25
OpenStudy (angela210793):
I agree with this''So 20 must = 80% of something ''
but i don't get this 1:''therefore 1% must be 20/ 80 which is 1/4''
OpenStudy (anonymous):
Ok it is because if 20 is 80% of something, we must divide 20 by 89 to find 1%, when we have that we multiply by 100. Ok?
