Question

express the following decimal in the form of p\q,(1)15.712 bar on 12​

Answer 1

Step-by-step explanation:

Let x = 15.712 [ 12 bar ]

x = 15.712121212-----

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 ]
