5 / 6 of a's work efficiency is equivalent to B's work efficiency. Here, the work of () is regarded as unit 1, and the work efficiency of () accounts for 5 / 6?

5 / 6 of a's work efficiency is equivalent to B's work efficiency. Here, the work of () is regarded as unit 1, and the work efficiency of () accounts for 5 / 6?

5 / 6 of a's work efficiency is equivalent to that of B. here, the work of (A's work efficiency) is regarded as unit 1, and the work efficiency of (B's work efficiency) accounts for 5 / 6

A project is completed by Party A alone for 10 days. The efficiency ratio of Party A and Party B is 3:2, and Party B alone for () hours
Wrong, the first sentence should be a project a alone to do 10 hours to complete

Solution 1:
The unit of work quantity is 1
Then the efficiency of a: 1 / 10
According to the conditions, the working efficiency of Party B is 1 / 15
The second time is 15 hours
Solution 2
Because the working efficiency is inversely proportional to the working time
Therefore, the working time ratio of Party A and Party B is 2:3
So the working time of Party B is: 10x3 / 2 = 15

For a job, it takes 8 days for Party A to do it alone and 10 days for Party B to do it alone. What is the time ratio of Party A and Party B? What is the efficiency ratio of Party A and Party B?

If Party A and Party B work together for several days, Party A will complete 1 / 8 in one day, and Party B will complete 1 / 10 in one day. Therefore, if Party A and Party B cooperate for 1 / 8 + 1 / 10 = 9 / 40 in one day, it will take 1 / (9 / 40) = 40 / 9 days to complete. The work efficiency ratio is 1 / 8:1 / 10 = 5:4

The ratio of work efficiency between a and B is 3:4. After 6 days of cooperation, a will work alone for 10 days to complete a project
How many days does it take for Party A and Party B to complete the project separately?

If the work efficiency of a is 3x, the work efficiency of B is 4x
(3X+4X)*6+3X*10=1
42X+30X=1
72X=1
X=1/72
Efficiency of a = 3x = (1 / 72) * 3 = 1 / 24
Work efficiency of B = 4x = (1 / 72) * 4 = 1 / 18
It will take 24 days and 18 days for Party A and Party B to complete the whole project separately

It takes 8 days for Party A to finish a job alone, and the efficiency of Party B is twice that of Party A. how many days can two people finish the job together?

A: it takes 223 days for two people to work together

Party A and Party B cooperate with each other in a work. Because of the good cooperation, the work efficiency of Party A and Party B is one tenth higher than that of Party A and Party B respectively
First, Party A and Party B worked together for six hours and completed two fifths of the whole work. The next day, Party B worked alone for six hours and left behind thirteen fifths of the work. Q: if Party A always does this work alone, how many hours will it take to complete it?
Urgent! Please!
Come on, I'm in a hurry!

B alone for 6 hours to complete 5 / 30;
If cooperation with Party A can improve the efficiency by 1 / 5, that is to say, in the case of cooperation, Party B can complete 6 / 30 in 6 hours
Two people cooperate for 6 hours, a total of 12 / 30, of which B 6 / 30, then a cooperation in the case of 6 hours is completed, the remaining 6 / 30
A's work efficiency can only be improved by 1 / 10 when working together, so when working independently, it can only complete 0.909/30 per hour
So a alone is 30 copies / 0.909 copies per hour, which takes 33 hours

It takes 10 days for a project to be completed by Party A and Party B. It is known that the work efficiency ratio of Party A and Party B is 2:3. How much does it take for Party B to complete the project alone
How many days will it take B to finish the project alone?

B efficiency = 1 / 10 ÷ (2 + 3) × 3 = 3 / 50
1 △ 3 / 50 = 50 / 3 days
B. it will take 50 / 3 days to complete the project alone

For a project, Party A and Party B cooperate to complete it in 8 days, and the efficiency ratio of Party A and Party B is 3:2. If the project is completed by Party B alone, how many days will it take?

A: if the project is completed by Party B alone, it will take 20 days

What is efficiency equal to

Work efficiency = total amount of work △ working hours
That's all

The 6-hour workload of worker a is equal to the 8-hour workload of worker B. what percentage of worker a's work efficiency is that of worker B?

The unit of 6-hour workload of a worker is "1"
Then the efficiency of a is 1 / 6 and that of B is 1 / 8
The working efficiency of worker a is the same as that of worker B
1/6÷(1/8)×100%=133.3%
