1 part = 3 units because there are 3/5 blue marbles left.
So, 3 parts = 9 units and 5 parts = 15 units.
Work backwards to find the number of units for each colour.
Compare the total number of units for 'At First' and 'At the End' --> they should be equal.
Hence, the different in 1 unit is equal to 54.
