Hint: Make both the denominators of both fractions equal 10, then multiply both numerators by the number you would need to make the denominator 10.
So, If you make 3/5 into 3/10, then you would need to multiply the 3 by 2, since 5x2=10. You do the same thing to the other fraction, 1/2 to 1/10, then you multiply the 1 by 5, since 2x5=10.
Then you just add 6/10 and 5/10 and there is your answer.
