x - 20%=20

OpenStudy (angela210793):

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

OpenStudy (anonymous):

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!

OpenStudy (anonymous):

What do you think?

OpenStudy (angela210793):

wow....idk...O.o

OpenStudy (angela210793):

may be tht though....

OpenStudy (anonymous):

Sorry does that mean you agree?

OpenStudy (angela210793):

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

OpenStudy (anonymous):

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?

OpenStudy (anonymous):

Sorry it is dark here! It shoul;d read 80 not 89

OpenStudy (angela210793):

yea i think i got it :)Thnx :)

OpenStudy (anonymous):
