Question

Express 0.57 bar as a fraction in simplest form ?​

Answer 1

Answer:let X=0.577777

multiply by 10 both sides

10x = 5.77777. ........(i)

multiply by 10 both sides

100x = 57.77777. .........(ii)

subtracting (i) from (ii)

100x-10x = 57.77777-5.7777

90x = 52

X= 52/90

Answer 2

Answer:

suppose x=0.5777.......................(1)

now multiply by 10 because after decimal there are two numbers which have bar.

so,10x=5.777............................(2)

now by subtracting equation 1 from eq. 2

we get,10x-x=5.777-0.5777

9x=5.2

x=5.2/9

thank you....
