How many numbers can I fill in the brackets?
1 in 6 = 25 in 150
1 / 5 = 30 / 150
Four numbers can be filled in the brackets
What are the numbers in brackets 3,3,9,6,27,9, (), ()
3,3,9,6,27,9,(81),(12)
3*3=9,9*3=27,27*3=81
3+3=6,6+3=9,9+3=12
3, 6, 9, (), (), (), 27 what numbers should be filled in brackets?
3 6 9 12 18 24 27
The above figures are multiples of 3
The numbers between 3 ^ 1 and 3 ^ 2 are even
The numbers between 3 ^ 2 and 3 ^ 3 should also be even
That is the multiple of 6: 12 18 24
There are 100 geese in the farm, which is 14 times the number of ducks and 49 times the number of chickens. How many chickens are there in the farm?
100 △ 14 △ 49, = 100 × 4 × 94, = 900 (chickens)
Today, a breeding factory raises 4400 chickens, 2000 ducks and 1600 geese, accounting for several percent of the total number of birds
Today, a breeding factory raises 4400 chickens, 2000 ducks and 1600 geese, accounting for several percent of the total number of birds
Chicken: 4400 / (4400 + 2000 + 1600) * 100% = 55%
Duck: 2000 / (4400 + 2000 + 1600) * 100% = 25%
Goose: 1600 / (4400 + 2000 + 1600) * 100% = 20%
Wang Dabo has 120 chickens this year. The number of geese is 4 / 5 of that of chickens and 2 / 3 of that of ducks?
Goose: 120 * 4 / 5 = 96
Ducks: 96 △ 2 / 3 = 144
So a total of: 120 + 96 + 144 = 360
The number of chickens raised in the farm is five times that of geese. There are 480 chickens and geese raised in the farm
Chicken 400, goose 80
If there are x geese, then there are 5x chickens
X plus 5x equals 480
So x equals 80
So chicken 400, goose 80
There are 2000 geese and chickens. One fifth of the geese are more than 10 percent of the chickens. Q: how many geese and chickens are there?
Set X geese and Y chickens
x+y=2000
1/5*x-30%y=10
2.5y=1950
Y = 780
X = 1220
There are 2000 chickens, geese and ducks in a specialized household, of which 60% are chickens. The ratio of ducks to geese is 3:1. How many geese are there
2000 x (1-60%) = 800 geese and ducks
Ducks 800x1 △ (1 + 3) = 200
800-200 geese = 600
The factory raises 200 chickens and 40 geese. The sum of the number of ducks and geese is exactly 4 / 5 of the number of chickens. How many chickens?
200
