Answer:


19(11)/(15)

Explanation:

We have the problem:


6(2)/(3) *2+3(1)/(5) *2

6 2/3 can be written as (6 + 2/3), and 3 1/5 can be written as (3 + 1/5). So, we can then use the distributive property:


(6+2/3)*2+(3+1/5)*2=12+4/3+6+2/5=18+4/3+2/5

Now, we need to combine the fractions by finding a common denominator. Here, the common denominator is 3 * 5 = 15:
4/3 +2/5=20/15+6/15=26/15=1(11)/(15)

Finally, we add 18 to 1 11/15:
18+1(11)/(15) =19(11)/(15)

Thus, the answer is
19(11)/(15).

Hope this helps!
