It is hoped that 2 male workers and 4 female workers in the factory can process all parts (3/10) in one day, and 8 male workers and 10 female workers can process all parts in one day. If you compare the processing of male workers alone with female workers alone, how many more female workers are there than male workers to complete the task in one day?
希望工厂里2个男工和4个女工在一天内加工全部零件的(3/10)，8个男工和10个女工在一天内可加工完全部零件．如果把单独让男工加工和单独让女工加工进行比较，要在一天内完成任务，女工要比男工多多少人？
