There are two warehouses of a and B. the grain in warehouse A is 30 tons. If 110 is taken out of warehouse A and put into warehouse B, the amount of grain in the two warehouses is equal. How many kilograms of grain are stored in the two warehouses?

There are two warehouses of a and B. the grain in warehouse A is 30 tons. If 110 is taken out of warehouse A and put into warehouse B, the amount of grain in the two warehouses is equal. How many kilograms of grain are stored in the two warehouses?

(30-30 × 110) × 2 = (30-3) × 2 = 27 × 2 = 54 (T) = 54000 (kg) a: the total grain stored in the two warehouses is 54000 kg
There are 1220 washing machines in warehouse A and warehouse B. 300 washing machines are transported by warehouse A and 80 washing machines are transported by warehouse B. the washing machines in warehouse A are better than those in warehouse B
Less than 200 sets. The original a, B two warehouses each have the number of washing machines
X+Y=1220
X-300=Y+80-200
X=700
Y=520
Let's set up a x and B y
x+y=1220
x-300=y+80+200
The results of solving equations
x=900，y=320
Is 1220 original or present
2. The number of washing machines in warehouse A is 200 less than that in warehouse B
If there are x washing machines in warehouse A, there are (x + 200) washing machines in warehouse B,
x-300 + x+200+80=1220
That is, 2x = 1240
The solution is x = 620
∴x+200=820
A: there are 620 washing machines in warehouse A and 820 washing machines in warehouse B
Is 1220 original or present
2. The number of washing machines in warehouse A is 200 less than that in warehouse B
If there are x washing machines in warehouse A, there are (x + 200) washing machines in warehouse B,
x-300 + x+200+80=1220
That is, 2x = 1240
The solution is x = 620
∴x+200=820
A: there were 620 washing machines in warehouse A and 820 washing machines in warehouse B.
Hope to help you! Put it away
There are x washing machines in warehouse A and (1200-x) washing machines in warehouse B
X-300+200=1200-X+80
The solution is x = 690, that is, 690 washing machines in warehouse A and 1200-690 = 510 washing machines in warehouse B.
A: there were 690 washing machines in warehouse A and 510 washing machines in warehouse B.
The number of a is two fifths more than that of B. what is the ratio of B to a, and what is the proportion of a to the sum of the two numbers?
Method 1: take number B as unit 1, then number a is 1 + 2 / 5 = 7 / 5
1：7/5=5：7=5/7.
The proportion of a number in the sum of two numbers: (7 / 5) / (1 + 7 / 5) = 7 / 12
Method 2: take the number B as 5, then the number a is 5 + 2 = 7, so the ratio of number B to number a is 5 / 7, and the ratio of number a to the sum of two numbers is 7 / (5 + 7) = 7 / 12
The first method: take number B as unit 1, then number a is 1 + 2 / 5 = 7 / 5. So, what's the ratio of B to a
1：7/5=5：7=5/7。
The ratio of the number of a to the sum of two numbers is (7 / 5) / (1 + 7 / 5) = 7 / 12.
The second method: take number B as 5, then number a is 5 + 2 = 7, so the ratio of number B to number a is 5 / 7, and the ratio of number a to the sum of two numbers is 7 / (5 + 7) = 7 / 12. From this we can get the result

1：7/5=5：7=5/7。

The number of male workers in a workshop is 8 / 9 of that of female workers. After adding one female worker, the number of male workers is 6 / 7 of that of female workers. How many male and female workers are there in the original workshop?
The formula must be correct. I'll add points
The number of male workers in a workshop is 8 / 9 of that of female workers. After adding one female worker, the number of male workers is 6 / 7 of that of female workers. There were 24 male workers and 27 female workers in the original workshop
Set the original number of female workers to be X. 8 / 9 * x = 6 / 7 * (x + 1)
56X=54X+54
X=27
The ratio of a to B is 2 to 5. What's the difference between a and B? What's the difference between B and a?
The difference between the two books is 2: (5-2) = 2:3 = 2 / 3;
If B is more than a, a = (5-2) / 2 = 3 / 2;
The difference between the number a and the number b = (5-2) / 2 = 3 / 2
Number B is more than number a = (3 + 2) / 2 = 5 / 2
Let a be x and B be y, then x / y = 2 / 5, that is, x = (2 / 5) y, so the first question is 2 / 3 and the second question is 3 / 2
There are 152 workers in a workshop. After one eleventh of the male workers and five female workers are selected to attend the training course, the number of the remaining male and female workers is just the same
How many men are there in this workshop? We need to solve the equation. We must write down the process of solving the equation step by step!
There are x male workers and (152-x) female workers in the workshop
（1-1/11）x=152-x-5
It's time to tidy up
21/11x=147
If we divide 21 / 11 on both sides of the equation, we can get,
x=77
∴152-x75
That is, there are 77 male workers and 75 female workers in this workshop
Well, female workers don't ask for it
Hope to help you!
If the ratio of the number a to the number B is 4:5, then the number a is the number B______ B is the sum of a and B______ .
Number a is number B: 4 △ 5 = 45; number B is the sum of number a and number B: 5 △ 4 + 5 = 5 △ 9 = 59; answer: number a is 45 of number B, number B is 59 of the sum of number a and number B; so the answer is: 45, 59
There are 60 people in a workshop. The number of male workers is female workers. How many are male workers and female workers?
one-third
It's very simple. Boys are one third of girls, so there are four? Boys have one, that is, the number of boys is 60 * 1 / 4 = 15, girls have three, that is, 60 * 3 / 4 = 45
Enough details. Remember to step on mine
What's the female worker's? I didn't make it clear.
The number of male workers is one third of that of female workers
To put it simply, consider male workers as one and female workers as three
So the number of male workers is 60 / (1 + 3) = 15
The number of female workers is 15x3 = 45
The number of a is 1 / 5 more than that of B, and the number of B is a fraction less than that of A. the number of B is a fraction of the sum of a, B and two numbers
Let B be x, then a be 1.2x
So B is one sixth less than a
B is 5 / 11 of the sum of a and B
You can assume that a is 1.2 and B is 1
The number of B is less than that of a: (1.2-1) △ 1.2 = 1 / 6
The number B is the sum of a, B and two numbers: 1 / (1 + 1.2) = 5 / 11
Your question lacks a clear meaning. Number a is 1 / 5 more than number B. is it 1 / 5 of number B or 1 / 5 of number a?
Then there are two situations
Suppose 1: A is 1, the number of a is 1 / 5 more than that of B, then the number of B is 0.8. The number of B is 1 / 4 less than that of a, and the number of B is 0.8/1.8 of a, and the sum of B is 4 / 9
Suppose 2: B is 1, the number of a is 1 / 5 more than that of B, and the number of a is 1.2, then the number of B is 1 / 6 less than that of a, and the number of B is 5 / 11 of the sum of a and B.
I think the first one is the possibility of positive solution

I think the first is the possibility of positive solution..... Follow up: I can't help the teacher's questions, or I'll ask you what's wrong,
There are 60 male workers in the first workshop, and the number of female workers is 3 / 4 of that of male workers. How many more male workers than female workers?
60 male workers, 60 female workers * 3 / 4 = 45
Male workers 60-45 more than female workers = 15
