OpenStudy (anonymous):

x = 2.12... 100x = 212.12... - x = 2.12... ---------------- 99x = 210 x = 210/99

OpenStudy (saifoo.khan):

53/25

OpenStudy (anonymous):

what? how did u get 53/25?

OpenStudy (saifoo.khan):

idk, my calc.

OpenStudy (anonymous):

It's not 53/25. Dividing something by 25 will never give you a repeating decimal.

OpenStudy (saifoo.khan):

Ok, lets go this time with Mooby..

OpenStudy (saifoo.khan):

i cant say anything.

OpenStudy (anonymous):

210/99 should be reduced to 70/33. Mooby has one of the correct fractions that could represent 2.121212...
