Question

express 0.235 bar and 1.27 bar in the form of p/q

Answer 1

0.235=235/1000 =47/200
1.27 bar = 125-1/99=124/99

Answer 2

Solution;-

(1) 0.235 bar

Let x = 0.235 bar = 0.235235  ...........(1)
Multiplying it by 1000, we get.
1000x = 235.235235  .........................(2)
Now, subtracting (1) from (2), we get.
999x = 235
x = 235/999

(1) 1.27 bar

Let y = 1.27 bar = 1.272727........................(1)
Multiplying it by 100, we get.
100y = 127.2727 ........................................(2)
Now, subtracting (1) from (2), we get
99y = 126
y = 126/99
y = 14/11
