Question

$express \: 0.123bar$

Answer 1

Hiii friend,

0.123 bar

Let X = 0.123

Then X = 0.123123123......(1)


Multiply equation (1) by 1000 we get

1000X = 123.123123123......(2)


Subtract equation (1) from equation (2)

1000X = 123.123123123
X. = 0.123123123
_________________

999X = 123

X = 123/999

Hence,

0.123 bar is in the form of 123/999 which is in the form of P/Q.


HOPE IT WILL HELP YOU..... :-)

Answer 2

Hello dear
answer is

$let \: \: x = 0.123 \: (bar \: \: on \: 23) \\ then \\ \\ = > x = 0.1232323 \: \: \: \: \: \: \: \: \: \: \: \: .......(1) \\ = > 10x = 1.232323 \: \: \: \: \: \: \: \: \: \: .......(2) \\ and \: \: \: 1000x = 123.232323 \: \: \: \: \: \: \: \: \: ....(3) \\ \\ on \: \: subtracting \: \: (2) \: from \: (1) \\ we \: \: get \\ \\ = > 990x = 122 \\ = > x = \frac{122}{990} = \frac{56}{495} \\ \\ hence \: 0.123 = \frac{56}{495}$
Hope it's helps you.
