Question

Express 4.127 bar in p/q form

Answer 1

x = 4.127 bar                   -1

1000x = 4127.127 bar     -2

Subtracting 1 from 2

We can say that

999x = 4123

x= 4123/999

Therefore 4.127 bar in p/q form = 4123/999

Answer 2

x = 4.127 bar                   -1

1000x = 4127.127 bar     -2

Subtracting 1 from 2

We can say that  

999x = 4123

x= 4123/999

Therefore 4.127 bar in p/q form = 4123/999
