Answer 1

Answer:

Let,

x = 1.272727

here two digits are repeating so we will multiply both sides by 100

100x = 127.27

Now subtract both sides

100x - x = 127.27 - 1.27

99x = 126

x = 126 / 99

14 / 11

Answer 2

Answer:

1739 / 99

Step-by-step explanation:

 Let 17.56( bar is on 56 ) = a

⇒ a = 17.$\overline{56}$      ...( 1 )

    Multiply both sides by 100 :

⇒ 100 * a = 100 * 17.$\overline{56}$

⇒ 100a = 1756.$\overline{56}$

   Subtract ( 1 ) from both sides:

 100a = 1756.$\overline{56}$

   -   a = -   17.$\overline{56}$

  99a = 1739

 ⇒ 99a = 1739

 ⇒ a = 1739 / 99

⇒ a = 17.56 bar = 1739 / 99
