see bro let me help and then plz mark as brainliest
Step-by-step explanation:
Let x = 1.272727272727.......
√√ firstly I'm going to tell you some information about this
√√ if there is one digit number afte bar or decimal then we multiply that no with 10
Eg - 0.9
√√ If there is two digit number after bar then we multiply by 100
eg - 1.27
√√ if there is three digit no after then we multiply by 1000
. Eg - 1.273
@ According to this question @
here is only two digit no
So
100 x will be 127.2727
we subtract 100x -x you will get this
100x - x = 127.2727 - 1.272727
99x = 126 .000
x = 126/99
hence your answer is 126/ 99
you can divide this if it is divisible
126/99 = 14/11
hence your answer is 14/11
hope it helps
