3/a/(1/b/5+6/b)=9/22
3/a/(5/b+6/b)=9/22
3/a/(11/b)=9/22
3a/11b=9/22
a/b=3/2
3/a/(5/b+6/b)=9/22
3/a/(11/b)=9/22
3a/11b=9/22
a/b=3/2

(3/a)/(5/b+6/b)=9/22
taking b/a common (3)/(5+6)=9/22
=>b/a=(9*11)/(22*3)
=>b/a=3/2 answer (d)
taking b/a common (3)/(5+6)=9/22
=>b/a=(9*11)/(22*3)
=>b/a=3/2 answer (d)
