Answer 2

${Answer :-}$

First method -

Let x = 3.456789123 bar

Now, we have,
1000000000x = 3456789123.456789123 bar

Or, 1000000000x = 3456789120 + 3.456789123bar.

Or, 1000000000x = 3456789120 + x

Or, 1000000000x - x = 3456789120

Or, 999999999x = 3456789120

Or, x = 3456789120/999999999.

OK, this is the actual method.

Now, let's take an look on this one,

Second method -

First write the number simply without any of decimal point.

3456789123

Now, subtract the remaining number on the left to the decimal point.

3456789123 - 3 = 3456789120

Now, take a 9 for each digit and a 0 for each digit onto the right of the decimal point.

Here, we have 9 digits which all have bar on them and no digits without bar, so we divide it by nine 9.

Thus, 3456789120/999999999

Hence, it is your required answer.
