A completes all 1 36 per day
B completes all 1 32 per day
A does it for 9 days, B does it for 14 days, a total of completed:
All that remains: 1-11 16 = 5 16
A and B cooperation is completed every day: 1 36 + 1 32 = 17 288 cooperation is completed, and it is also needed: 5 16 17 288 = 90 17 days.
-
A completed the project in 9 days.
1/36 9 1/4
B completed the work in 14 days.
1/32 14 7/16
A total of completed works.
1/4 7/16 11/16
There are still works left.
1 11/16 5/16
The rest of the project two people work at the same time and need to be completed.
5/16 (1/36 1/32) 90/17 (day).

Efficiency of A: 1 36 Efficiency of B 1 32
Finish: 1 36 9+14 1 32=1 4+7 16=11 16
Remaining: (1-11 16) (1 36 + 1 32) = 90 17
-
From the meaning of the title, it is known that the work efficiency of A is 1 36, and the work efficiency of B is 1 32 The completed project: 1 36 * 9 + 1 32 * 14 = 11 16 The work efficiency of two people at the same time is 1 36 + 1 32 = 17 288, and the time required is (5 16) (17 288) = 90 17 days.
Why is it so bt number Uh...

x+solution:x=
x=test: Substitute x= into the equation and make a noise.
Left = Right.
So, x= is the solution of the equation.

Solution: 6 50 300 meters.
300 6 5 300 seconds.
5 300 1500 meters.
1500 6 250 seconds.
A: It now takes 250 seconds for Chubby to complete the race.
-
Now there are 96 4 = 24 per bag.
Bring back what was transferred out, and bring back what was transferred back again.
B originally had 24-6+6=24.
-
Backwards. A, B, C, D.
Bag B originally had 24 pieces.
-
According to the inscription, the time ratio of B and C is 45:50 = 9:10, that is, the velocity ratio is 10:9.
The time ratio of A and B is 60:75 = 4:5, that is, the velocity ratio is 5:4, and the velocity ratio of A, B and C is 25:20:18.
The velocity ratio of A and C is 25:18.
Find the ratio.
-
The remaining two-thirds were processed the next day, and (1-1 4)*2 3=1 2 of the total were processed
There are a total of 90 (1 2-1 4) = 360 parts in this batch.
-
Let the total number be 1, then 1/4 will be processed on the first day, and 3/3 of 2/2 will be processed on the second day, which is 1/2 Answer: 4 1x=2 1x-90 Result x=360 x is the total number of parts I don't know what you can read.
The above methods are all algorithms with equations, 75=2100 (meters) It is also the deformation method of equations, which is not practical for elementary school students who are not good at equations, and the general primary school students feel that the reasoning learning method is easier to use and easy to understand than equations, so I will use a reasoning method to solve this problem! >>>More
The volume of the cuboid length, width, and height, after analyzing the meaning of the question, we will find that the length, width, and height of the cuboid cannot be directly calculated from the known conditions in the question. At this time, we might as well start from the known conditions and find another shortcut to solve the problem. Now let's analyze it together: >>>More
