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 52 and 25 to both fractions. 62/52 simplifies to 12/10. Lets do the same to the other fraction except using 5 this time. We now get 55/25 = 25/10. We can now multiply across. 2512/10*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.
