So we need to find:

If we want to express it as a simple fraction we need both terms to be expressed like fractions so let's take 2.6 and turn it into a fraction with 10 as the divisor:

Where I use the fact that 10/10 equals 1 so I could "make it apear" multiplying 2.6. Now we write and solve our quotient:

So the answer is 33/10
