#3/5#

Explanation:

#a/b+-c/b=(a+-c)/b#

In other words, adding or subtracting two separate fractions that each have the same denominator is the same thing as adding or subtracting the numerators, all over that same denominator.

#9/10-3/10=(9-3)/10=6/10#

Simplifying by dividing the numerator and denominator by the greatest common factor of the numerator and denominator, we get #6/10=(6/2)/(10/2)=3/5#.
