Question

Express 1.272727...... as rational number in the form p/q.

Answer 1

Hi ,

Let x = 1.272727....------( 1 )

Multiply ( 1 ) with 100 we get

100x = 127. 272727... ----( 2 )

Subtract ( 1 ) from ( 2 ) we get

99x = 126

x = 126/ 99

x = ( 9 × 1 4)/ ( 9 × 11 )

After cancellation

x = 14/11 ( p / q form )

Therefore

1.272727...= x = 14/11

I hope this helps you.
