See below.

Explanation:

Half of nine tenths can also be expressed as #1/2 * 9/(10)#. In case you didn't know or don't remember, whenever you see the word "of" in mathematics, it usually means multiplication. So when you are given "half of nine tenths in fraction form," we can rewrite this as half, or #1/2#, times #9/10#.

Now, let's actually multiply #1/2# by #9/10#:

#1/2 * 9/10#

#(1*9)/(2*10)#

#9/20#

I hope that helps!
