First, add 3+3 which is 6/5. Next, you use KCF. 6/5 * 5/2. You now have to find a least common denominator. You can multiply 5*2 and 2*5 to both fractions. 6*2/5*2 simplifies to 12/10. Lets do the same to the other fraction except using 5 this time. We now get 5*5/2*5 = 25/10. We can now multiply across. 25*12/10*10. 300/100 which reduces to simply 3. You can double check this on a scientific calculator like I did and got the same answer.
