The equation goes like this......
first cross multiply a/9x9/20 where u'll get a/20
next cross multiplying a/20x4/9 will result a/45
now u'll have a/45=1/9 which simply will end up again cross multiplying 9a=45
and then u'll get a=45/9
= 5
Hope it helped .... :) !!

a/9*9/20= a/20
a/20x4/9= a/45
a/45=1/9
a=1/9*45=5
a=5
