Answer:
6 14/15
Step-by-step explanation:
I would say simplifie the paratensies.
First:
3 2/3+ 17 1/5 =
Common factor of 3 and 5 is 15
3 10/15 + 17 3/15 = 20 13/15
Second:
11 3/5 + 2 1/3 =
Common factor of 3 and 5 is 15
11 9/15 + 2 5/15 = 13 14/15
20 13/15 - 13 14/15 = 7 13/15 - 14/15 = 7 - 1/15 = 6 14/15
It’s the second answer. 2•10•2 + 2•10•3 + 2•2•3
