The answer would be 80 because you are multiplying each number by 2. You multiply 5 x 2 = 10, 10 x 2 = 20, 20 x 2 = 40, and then 40 x 2 = 80. That is how I got the answer 80!!
Find a common demoninator for example 6 because all of the denominators can go into 6 then you should find your answer quite easily when u add the fractions because all you have to do is add the numerator together to get to 2/3 (4/6)
