Someone for brainiest and .. no fake answers or you get reported

Hello from MrBillDoesMath!

12/5

Discussion:

Note that 10 is a common denominator of both denominators:

9/5 = (9*2)/(5*2) = 18/10

- ( -6/10) = + (6/10)

So the original problem is equivalent to

18/10 + 6/10 =

(18 +6)/10 =

24/10 =

(2*12)/ (2*5)   =>       cancelling the common factor "2"

12/5 =

2 and 2 fifths =

22/5            (though this looks like (22)/5!)

Thank you,
