please 2 aur 3 part ko full solution k sath de dooo​

Answer 1

Step-by-step explanation:

1). let x = 0.66666... (a)

and multiplying both sides by 10

10x = 6.66666.... (b)

subtracting (a) from (b), we get

10x = 6.66666...

- x = 0.6666...

9x = 6

x = 6/9

x = 2/3

2). let x = 0.4777777...

and multiplying both sides by 10

10x = 4.777777... (a)

multiplying both sides by 100

100x = 47.77777... (b)

subtracting (a) from (b)

100x = 47.7777...

- 10x = 4.7777...

90x = 43

90x = 43

x = 43/90

Multiply x by such a value (10,100,1000...) that the recurring (non terminating) digit i.e digit having bar comes after the decimal place.
