i ) let x = 0.2323---( 1 )

Multiply equation ( 1 ) with 100, we get

100x = 23.2323-----( 2 )

Subtract ( 1 ) from ( 2 ) , we get

99x = 23

x = 23/99 ----( 3 )

ii ) Let y = 0.2222----( 4 )

Multiply equation ( 4 ) with 100,

100y = 22.2222-----( 5 )

Subtract ( 4 ) from ( 5 ) , we get

99y = 22

y = 22/99 ----( 6 )

Therefore ,

0.23bar + 0.22bar

= x + y

= 23/99 + 22/99

= ( 23 + 22 ) / 99

= 45/99
= 5/11

The two rational number between 3.5 and 3.6 are 35/ 10 , 36/10 So we can multiply 10 to the both sides 35/10* 10/10 , 36/10 * 10/10 = 350/ 100, 360/100 There are exact ten rational number between it
