heres a neat trick that i was shown ~ 2=1 impossible rite?

let 2 be a and 1 be b

a=b
(start)
2a=a+b
(add a to both sides of the equation)
2a-2b=a-b
(take away 2b)
2(a-b)=(a-b)
(group like terms)
2=1
(simplify)

I mean, replace the variables right from the start because you have already been shown the values. Meaning:
a = 2
b = 1
a=b ~ 2=1
so there's no need to do all that O.o

u can call me wot eva

ok 2 convert non repeatin decimals into fractions u frist hav 2 no ur places

eg. 0.000001

(colour coded) ones, decimal, tenths, hundredths,thousandths, ten thousandths, hundred thousandths, millionths and so on etc (that was a lot of work)

anyway say u had a number like 0.23 u look at the last number which is 3 and u figure out wot place it is in (hundredths) then u place the number after the decimal point over the place. So it becomes 23 over 100 or 23/100

this is my first time answerin a request from a student so i dont no how well i am just ask me if u still don understand and ill try and help u or maybe ill just give up ...
