Question

express 15.712 with bar on 12 in p/q form

Answer 1

5.712121212.............
multiply with 10 both sides , 
10x = 157.1212121212..............------(1)
again, multiply with 1000 both sides , 
1000x = 15712.1212121212...........------(2)
subtract equation (2) - (1) 
1000x - 10x = 15712.121212.... - 157.121212....
990x = ( 15712 - 157) = 15555
x = 15555/990 
Hence, 15555/990 in the form of P/Q of 15.712[ 12 bar ]
