2/5＜2/3
After typing the same manuscript, it took two fifths of an hour for Party A and two thirds of an hour for Party B. the efficiency of Party A is high
A manuscript, a typist 3 hours, B typist 4 hours, write the ratio of a and B working hours, and then
Write down the work efficiency ratio of Party A and Party B
4:3 because Party A finishes in 3 hours, the work efficiency is equal to the total amount of work divided by the working hours. Suppose the total amount of work is 1, the work efficiency of Party A is 1 divided by 3, which is equal to 1 / 3, the work efficiency of Party B is 1 / 4, and the work efficiency ratio of Party A and Party B is 1 / 3: 1 / 4 = 4:3
