To find the answer to this question, we need to find the common denominator for 3/5 and 2/3.
The easiest way to do this is to multiply the denominators by each other.
5*3=15
Now, all we have to do is multiply the numerators by what we multiplied the denominators by, to make it equal.
3*3=9
2*5=10
Now all we have to do is add.
9/15+10/15=19/15 or 1 and 4/15.
Hope this helps!
