Question

geometric series to express 0.555.... as a rational number

Answer 1

0.555.. = 0.5 bar

Let 0.5 bar =x

As there is one number under bar, multiply by 10 on both sides,

10*0.5 bar = 10*x

5.5 bar = 10x
-0.5 bar = -x.

(Subtract x from both sides)
--------------------

5 =9x (bar will cancel)

5/9 =x

Then,

0.55... In rational numbers is 5/9
