Question

please help me slove this question

Answer 1

Let x= 0.777.. which is equal to 0.7
10x= 7.7
now 10x - x = 7.7 - 0.7
9x = 7
x=7/9


Again Let x = 4.83
10x= 48.3
100x= 483.3
100x - 10x = 483.3 - 48.3
90x= 435
x =435/90(you can simplify this)

3rd one is same as 2nd one just take 10x and 1000x you will get your result

Answer 2

x = 435/ 90
