Question

Express in form of p/q 0.00375 on 75 bar

Answer 1

let x=0.00375 on 75 bar - eq.1
multiply by 10
10x = 0.0375 on 75 bar - eq.2
multiply by 10
100x =0.375 on 75 bar - eq.3
multiply by 10
1000x =3.75 on 75 bar - eq.4
multiply by 10
10000x = 37.575 on 75 bar -eq. 5
multiply by 10
100000x = 375.75 on 75 bar -eq.6
from eq.6 and eq.4
100000x-1000x =3.75 on 75 bar -375.75 on 75 bar
99000x =373
x=373/99000
