We have 8/27 + 25/9 = 24/81 + 225/81 = 249/81 = 3.07;

let us first plug the values of r and s here
r=14 and s=8

Now here we can cancel 14 and 7 as 7*2 =14 , also we can cancel 8 and 8 as 8*1 is 8, so our simplified new form is:

Now we can multiply 3*2 and 5*1
3*2 =6
5*1=5
Next we add the two numbers
6+5 =11
So this is how we get the answer 11
The answers are, from 7 to 14,
11/3
50/6
49/6
18/8
11/2
7/4
26/5
14/6
