Question

express 15.712 with bar on 12 in p/q form

Answer 1

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 ]

Answer 2

Answer:

Step-by-step explanation:

Let x = 15.712 [ 12 bar ]

x = 15.712121212.............---(1)

multiply with 10 both sides ,

10x = 157.1212121212..............------(2)

again,

multiply with 1000 both sides ,

1000x = 15712.1212121212...........-(3)

subtract equation (3) - (2)

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 ]
