Question

$0.6))))))))$
​

Answer 1

Answer:

0.66666666... = 2/3

Step-by-step explanation:

Let x=0.66666666.... (i)

10x=6.66666666.... (ii)

(•since the bar is on one number, we multiply x with 10¹ = 10 )

Subtract (i) from (ii)

= 10x - x = 6.66666666 - 0.66666666

= 9x = 6

= x = 6/9

= x = 2/3
