I am trying to figure out:

44.91 Units equals 59% of the total

23.40 Units equals 41% of the total

This would mean the 23.40 Units are worth more per Unit. I cant figure out how many percent more are they per Unit.

The second question would be if I add 2.85 Units of the same value to the 23.40 Units for a new total of 26.25 what would the new percentages be?

44.91=?% and 26.25=?%.
