There are several tons of grain in warehouse A and warehouse B. after one fifth of the grain is transported from warehouse A to warehouse B, one fourth of the grain is transported from warehouse B to warehouse a At this time, the grain stocks of warehouse A and warehouse B are equal. How much of the original grain of warehouse A is that of warehouse B

There are several tons of grain in warehouse A and warehouse B. after one fifth of the grain is transported from warehouse A to warehouse B, one fourth of the grain is transported from warehouse B to warehouse a At this time, the grain stocks of warehouse A and warehouse B are equal. How much of the original grain of warehouse A is that of warehouse B

If the grain stocks in warehouses A and B are equal, the unit is 1
Then 1 / 4 of warehouse B will be transported to warehouse A, and warehouse B will have 1 (1-1 / 4) = 4 / 3
1 + 1-4 / 3 = 2 / 3
So the original warehouse A has 2 / 3 (1-1 / 5) = 5 / 6
B warehouse has 1 + 1-5 / 6 = 7 / 6
So the original grain in warehouse A is 5 / 6 △ 7 / 6 = 5 / 7 of that in warehouse B
That's five out of seven
Happy Spring Festival!
A is seven fifths of B
There are 135 workers in a factory, of which two-thirds are male workers and 98 are female workers. How many are male workers and female workers?
fast
Male workers = (135-98) / (1-2 / 3) = 111
Female workers = 135-111 = 24
The average of the three numbers of a, B and C is 120. The ratio of a, B and C is 3:4:5. What are the numbers of a, B and C?
The length of a cube is 25 decimeters. Change it into a cuboid. The ratio of length to width to height is 2:1:2. What is the length to width and height
Please use the method of the first semester of the sixth grade instead of the equation
1、
3+4+5=12
Sum of a, B and C = 120 × 3 = 360
A = 360 △ 12 × 3 = 90
B = 360 △ 12 × 4 = 120
C = 360 △ 12 × 5 = 150
 
2、
Sum of length, width and height = 25 × 12 △ 4 = 75 decimeters
2+1+2=5
Length = height = 75 △ 5 × 2 = 30 decimeters
Height = 30 △ 2 = 15 decimeters
 
There are 135 workers in a factory, of which 23 are male workers and 45 are female workers. The total number is 98. How many are male workers and female workers?
Suppose that there are x male workers, then: (135-x) × 45 + 23x = 98 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 215x = 10 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & n
The sum of a and B is 120. One fourth of a is 3 / 4 of B. how much is a and B
Number A: number B
=3/4：1/4
=1：3
A = 120 (1 + 3) = 30
B = 120-30 = 90
A is three times as much as B, so a is 90 and B is 30
1 / 4 of a number is 3 / 4 of B number
A = 3 B
B = 120 (3 + 1) = 30
A = 120-30 = 90
Thank you!
A 90, B 30, a total of 120, 1 A is equal to 3 B
Let a be x, then B be (120-x), & # 188; X = & # 190; (120-x), x = 90, then a is 90 and B is 30
Let a be x and B be y
x y＝120
1／4x＝3／4y
The solution is x = 90, y = 30
There are 135 workers in a factory, of which 23 are male workers and 45 are female workers. The total number is 98. How many are male workers and female workers?
Suppose there are x male workers, then: (135-x) × 45 + 23x = 98 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & 108-45x + 23x = 98 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 215x = 10 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 75.135-75 = 60. A: there are 75 male workers and 60 female workers
One third of a is equal to one fourth of B. If a is 120, what is B?
One third divided by one fourth
There are 135 workers in a factory, of which 23 are male workers and 45 are female workers. The total number is 98. How many are male workers and female workers?
Suppose there are x male workers, then: (135-x) × 45 + 23x = 98 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & 108-45x + 23x = 98 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 215x = 10 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 75.135-75 = 60.

The sum of a and B is 120, and a is one third of B. what are the two numbers?
Suppose a is x, B is y. x + y = 120, x = 1 / 3Y, y = 90, x = 30, a is 30, B is 90
Let a be x, then x + 3x = 120, x = 30, 3x = 90, so a is 30 and B is 90
There are 135 workers in a factory, two-thirds of which are male workers and 98 are female workers?
135-98 = 37 (1 / 3 of male workers)
37 / (1-2 / 3) = 37 / (1 / 3) = 111 (male workers)
135-111 = 24. (female worker)
