to make both fractions equal in to do the equation, we must make both of the denominators the lowest common multiple, that being 15 in this case. since we multiplied each of the denominators by the opposing denominator, we must therefore do the same to the numerators. because of this, 1/3 becomes 5/15 and 2/5 becomes 6/15. now we add the numerators together to get 5+6=11. the final answer is now 11/15.
