Question

Express 0.123( bar on 3) in the form p/q

Answer 1

Step-by-step explanation:

$\huge \boxed { \fcolorbox {green}{purple}{good morning}}$

question:

express 0.123 in the form of p/q

solution:

let 0.123 be x,

=>10x = 1.23

=>100x=12.3..............................(1)

=>1000x=123.3.........................(2)

now, subtracting 1 from 2,

1000x-100x=123-12

=> 900x=111

=> x = 111/900

thus, on expressing as p/q , the value comes as :

111/900

$\huge \boxed { \fcolorbox {green}{orange}{thank you}}$
