We've showed you how to add fractions and find a common denominator. Now, it's your turn. How do YOU think this problem can be solved? 
find the common denominator,then add the fractions!The common denominator can be 21 because 1/3 times 7=7/21 and 4/7 times 3=12/21.So,7/21+12/21=19/21!That is the answer.
