A job is completed in 6 days by Party A and 8 days by Party B. the work efficiency of Party A is a little faster than that of Party B jing
（1/6-1/8）÷1/8
＝1/24÷1/8
＝1/3
Mathematics problem is a project, a alone to do 6 days to complete, B alone to do 8 days to complete, a and B work efficiency ratio?
The work efficiency ratio is 4:3
Analysis: regarding the project as "1", if Party A wants to complete the project in 6 days, then Party A will complete 1 / 6 of the project in one day and Party B will complete 1 / 8, that is, the work efficiency ratio of Party A and Party B is 1 / 6:1 / 8 = 4:3
