#1/2#

When you add fractions they can be added when they have a common denominator. The numerator is what gets added:

#7/18 + 2/18 = (7+2)/18 = 9/18#

Then you need to reduce the fraction by dividing both numerator and denominator by the largest common factor #9#:

#9/18 -: 9/9 = 1/2#

#1/2#

Since we have the same denominators, we can just add the numerators. We get

#9/18#, which simplifies to #1/2#.

Hope this helps!
