Answer 2

Answer:-

1.3(bar on 3)

Example:- a.pqrs (bar on rs)

(apqrs-apq)÷9900(here how many digits are having bar those many nines in the denominator , how many numbers without bar after decimal point those many zeroes in the denominator) .

Now ,

(13-1)÷9

Because ,

1.3(bar on 3)=a.b(bar on b)

(ab-a)÷9(because there is only one number with bar after decimal point)

(13-1)÷9=12÷9=4÷3 .

This is the shortcut method for this .

Hope it helps you .
