Roosters to chickens is 2 to 8
That means where there are 2 roosters, there are 8 chickens.
Simplify the ratio 2:8
The ratio can be simplified to 1:4
So, for 1 rooster, there are 4 chickens.
Now, the question says that if there are 5 roosters, how many chickens will there be?
1 rooster to 4 chickens
5 roosters to ? chickens
We went from 1 rooster to 5 rooster. We multiplied by 5.
To find out how many chickens there are for 5 roosters, multiply 4 chickens by 5.
4 * 5 = 20
Where there are 5 roosters, there will be 20 chickens.
Another way to solve is as follows:

Answer:
Step-by-step explanation :
N = number of nickels
D = number of dimes
Q = number of quarters
`
252 = N + D + Q <---- Equation 1
D = 3(N+Q) <---- Equation 2
24.85 = 0.05N + 0.10D + 0.25Q <---- Equation 3
We a have set of three linear equations to solve for three unknowns N, D, and Q.
Rearranging the equations we have :
N + D + Q = 252
3N - D + 3Q = 0
0.05N + 0.10 D + 0.25Q = 24.85
Solving the set of linear equations, we end up with :
N = 49
D = 189
Q = 14
