Verified Answer :

to solve this, we need to simply multiply across

you have  5/6    5/9   so you need to do 5 5 , which is 25, and 6 9 , which is 54.
you now have the fraction  25/54

we know 5
5 is 25, and 1 * 25 is 25. we also know that 54 is not divisible by 5.
the fraction 25/54 is in its simplest form


I THINK ITS 5/9 more than likely im wrong but just trying to help
