Question

express 0.85 of 5bar in p/q form

Answer 1

bonjour dear!

0.85 bar

let x= 0.85 bar

x= 0.8555.......... equation 1

equation 1 *10= 10x= 8.5555....... equation 2

equation 2 - equation 1 = 9x = 7.7

x= 7.7/9

we should remove that point to make it in p/q form

so 7.7*10/9*10

x= 77/90 is the answer

hope it helps
