To find the answer, we want to find a value larger than 1/2 because we know that Mike drank more than 1/2 of the juice. First, we can say that 1/2 is the same as 2/4, after we multiply the numerator and denominator by 2.
Then, to find a fraction that is more than 1/2 but less than 1 (because 1 would represent all the juice), we can add 1/4 to 2/4 (1/4+2/4) to get 3/4 which is more than 1/2.
Hope this helps.
