Good observations. Look at how much easier it would be to solve this version of the Martian potatoes problem which avoids percentages altogether: Earth has developed an insatiable appetite for Martian potatoes with their tasty pulp. Yuki runs a successful manufacturing plant on Mars which synthesizes a product called 'Martian Instaspuds'; instant potatoes being more cost effective to ship. Now these red potatoes (it's Mars after all) are processed in lots of 100kg mass which consist of 1kg pulp to 99kg water, 1p:99w. For 'Instaspuds' this ratio must be reduced to 9p:1w. How much water must be boiled-off in solar powered kilns on the Martian equatorial surface to achieve this ratio? 1) posit the pulp mass remains constant at 1kg 2) x = end product mass; 9/10 x = 1kg; x = 10/9 kg; 1/9 kg = final water mass in resulting mixture 3) subtract
