This equation equals 0.000... when i make this formula, that should equal 0.11, when you calculate it on paper, step for step. What have i done wrong

 

(((1.45-1)*(100/1.45))-((100-(100/1.45))))/(1.45-1)

(((1.45-1)*(100/1.45))-((100-(100/1.45))))/(1.45-1)  simplify

[(.45)*(100/1.45) - 100 + (100/1.45)] / .45 =

[(45/1.45) - 100 + (100/1.45)] / .45 =  

[multiply the top and bottom of both fractions in the numerator by 20]

[900/29 -  100 + 2000/29] / .45 =

[ 2900/29 - 100] / .45  =

[100 - 100] / .45 =

0 / .45 = 

0

And there you go....

BTW......this isn't an "equation"..it's just an "expression"....
