Answer:
+

Explanation:
In the picture in pink, you had 1 3/5. You have one whole pink and then 3 of the 5 rows in pink. These 5 rows were cut up to make them into 15 small squares. Now, instead of have 3 out of 5 sections in pink, we now how 9 out of 15 sections in pink.
In the picture in blue, you had 1 1/3. You have on whole pink and 1 out of 3 columns, blue. They cut the picture up into 15 smaller squares. Now, instead of having 1 out of 3 sections in pink, we now have 5 out of 15 sections in pink.
Now that the pieces are the same size, we can add them together.
1
+ 1
= 2
