(r+5 )/3=9
(r+5)/3 × 3 = 9 × 3
r+5 = 27
r + 5 -5 =27- 5
r= 22
r+5/3=9
start by solving 5/3 which as a mixed number equals 1 2/3
them adding 1/3 to the mixed number gives you a whole number of 2
so far r=1/3
but then you take 9-2 and see how many more numbers you need to get 9
9-2=7 
R=7 1/3 or 22/3
