Question

p/q= 11/12,p/r= 9/8,q/r=?

Answer 1

we can write p/q as p/r divided by q/r we get p/r x r/q

r and r get cancelled we will get p/q so we can write p/r/q/r

= 11/12 divided by 9/8 we get 11/12 x 8/9

=22/27

therefore p/q is 22/27

hope its helpful @.@

Answer 2

Q / R = P/R / P/Q = 9/8 / 11/12 = 9*12 / 8*11 = 27/22.
