There are 3600 TV sets in warehouse A and B. If 15 sets are taken from warehouse A and put into warehouse B, the number of TV sets in warehouse A and B is equal. How many TV sets are there in warehouse A and B?

There are 3600 TV sets in warehouse A and B. If 15 sets are taken from warehouse A and put into warehouse B, the number of TV sets in warehouse A and B is equal. How many TV sets are there in warehouse A and B?

A: there are 2250 TV sets in warehouse A and 1350 TV sets in warehouse B
Warehouse A and warehouse B are 20 tons more than warehouse B. after warehouse A gives warehouse B 1 / 5, warehouse A and warehouse B are equal, how many tons of warehouse A and warehouse B are equal
A: 20 (1 / 5 × 2) = 50 tons
B: 50-20 = 30 tons
There were 20 △ 2 △ 1 / 5 = 50 tons in warehouse a
There were 50-20 = 30 tons in warehouse B
Have a good time
If the number a is 4 / 5 of the number B, then what is the number B? What is the sum of the number a? The number a is 2 / 3 more than the number B
The number a is 4 / 5 of the number B,
Let B be 5x and a be 4x
So number B is 5 / 4 of number a (1.25 times)
B is 5 / 9 of the sum of a and B
Because the number of a is 2 / 3 more than that of B
So 5x-4x = 2 / 3
x=2/3
So the number a is 10 / 3
B is 8 / 3
The number a is 4 / 5 of the number B
Number a + number b = number B + four fifths of number B
B = four fifths of a
In a workshop, the number of male workers is 2 / 5 more than that of female workers, and the number of female workers is a little less than that of male workers;
The number of male workers in a workshop is 2 / 7 less than that of female workers. How many times more are female workers than that of male workers?
The number of male workers in a workshop is 2 / 7 less than that of female workers
Male: female = (1-2 / 7): 1 = 5:7
Women are more than men (7-5) / 5 = 2 / 5
The number of male workers in a workshop is 2 / 5 more than that of female workers, so female workers are regarded as unit 1
Male Turner is 1 + 2 / 5 7 / 5
(7/5-1)/7/5
=0.4/7/5
=2/7
7x for male and 5x for female
1-5X/7X=2/7
3 / 5 of a is 50% more than B, 3 / 4 of B is 2 / 5 of C, then a: B: C = ()
Let B be 1
A1.5 * 3 / 5 = 9 / 10
C 3 / 4 * (5 / 2) = 15 / 8
So (9 / 10:1:15 / 8) = 36:40:75
In a workshop, the number of male workers is 25% more than that of female workers, and the number of female workers is 25% less than that of male workers?
The unit number of female workers is 1, and that of male workers is 1.25
(1.25-1)÷1.25=20%
One
There are x female workers. There are 1.25x male workers
So (1.25x-x) / 1.25x = 0.2
The number of male workers is 25% more than that of female workers, that is, the number of male workers is one fourth more than that of female workers,
In unit "1", the number of female workers is divided into four, while the number of male workers is five.
The number of female workers is one less than that of male workers,
The number of female workers is less than that of male workers by several percent. Divide the number of female workers less than that of male workers by the number of male workers
(5-4)/5=20%
Or: female worker is unit 1, male worker is (1 + 25%) = 125%
(125% - 1) △ 125% = 20%... Expansion

If the number a is two fifths more than the number B, how much less is the number B than the number a?
Number A: number B
=(1 + 2 / 5): 1
=7 / 5: 1
=7:5
So:
Number B is less than number a
=(7-5)÷7
=Two out of seven
The number of a is two fifths more than that of B,
The ratio of a to B = 1 + 2 / 5: 1 = 7: 5
How much less number B than number a?
=(7-5) △ 7 = 2 / 7
Let B be 5, then a be 5 + 2 / 5 × 5 = 7;
=(7-5)/7=2/7;
Less than 2 / 7;
If you have any questions, please ask~~
The number of a is 2 / 5 more than that of B, and the number of B is 2 / 7 less than that of A
Method 1: 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.
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. ... unfold

There are 66 students in the school chorus and dance team. Two fifths of the students in the chorus is equal to six fifths of the students in the dance team?
Hello:
Chorus number: dance team number = 6:7, 2:5 = 15:7
15+7=22
Chorus number = 66 △ 22 × 15 = 45 (people)
Number of dancers = 66-45 = 21
The number of a is 2 / 3 more than that of B. the number of B is equal to ()
The number of a is three times more than that of B
The number a is equal to 5 / 8 of the sum of two numbers
(1+2/3)÷(1+2/3+1)=5/8
B is equal to (3 / 5) of a
1÷(1+2/3)=3/5
The number of a is equal to 5 / 3 of the sum of two numbers
B is equal to 3 / 5 of A
Let B be 1, then a be 1 + 2 / 3 = 5 / 3
The number a is equivalent to the sum of two numbers: 5 / 3: (1 + 5 / 3) = 5:8
Number B is equal to number A: 1:5 / 3 = 3 / 5
The first empty 8 / 3
The second empty 3 / 5
There are 150 fewer boys than girls. Two thirds of girls are equal to five sixths of boys?
There are x girls and X-150 boys
2/3x=5/6(x-150)
2/3x=5/6x-125
2/3x-5/6x=-125
-1/6x=-125
x=750
There are 750 girls and 750-150 boys = 600
Female male = 150
Female * 2 / 3 = male 5 / 6
The two forms are simultaneous
Female = 750
Male = 600
Girls × 2 / 3 = boys × 5 / 6
Female: male = 5:4
So, the number of people per copy: 150.
Female: 150 × 5 = 750
Boys: 150 (4 × 600)
Let each student be x and y
y-x=150
2/3y=5/6x
The solution is x = 600
y=750
I hope I can help you
Set X for girls and y for boys
2/3x=5/6Y (1)
X-Y=150 (2)
We get x = 150 + y
Bring x = 150 + y into (1)
2 / 3 (150 + y) = 5 / 6y
Y = 600
X=750
