Answer:

9

Step-by-step explanation:

Simplify before multiplying to make things easier.

\frac{1}{9}* \frac{81}{1}  

you can cross-simplify 9 and 81, which simplifies to:

\frac{1}{1}*\frac{9}{1}

\frac{1}{1} is equivalent to 1 and \frac{9}{1} is equivalent to 9, so all you're really doing is multiplying 9*1

9*1 = 9

so 1/9 * 81/1 is just 9.
