farmer bill has 28 chickens, 15 ducks, and 7 turkeys. he sold 4/5 of the birds. if he sold 12 chickens, what fraction of the chickens are left
To find out what fraction of the chickens are left, we need to determine how many chickens Bill has left after selling 4/5 of the birds.
The total number of chickens Bill originally had is 28. He sold 4/5 of them, which means he sold (4/5) * 28 = 112/5 chickens.
If Bill sold 12 chickens, then he has (28 - 12) = 16 chickens left.
Therefore, the fraction of chickens left is 16/28, which can be simplified to 4/7.
To find the fraction of the chickens that are left, we need to determine the total number of chickens initially and subtract the number of chickens that were sold.
We are given that Farmer Bill has 28 chickens. However, he also sold 12 chickens. So, we subtract the number of chickens sold from the total number of chickens:
28 - 12 = 16
Therefore, Farmer Bill has 16 chickens left.
To express this as a fraction, we need to create a fraction with the number of chickens left as the numerator and the initial number of chickens as the denominator:
Fraction of chickens left = (Number of chickens left) / (Initial number of chickens)
= 16 / 28
Now, let's simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 4:
16 / 28 = (16 ÷ 4) / (28 ÷ 4)
= 4 / 7
So, the fraction of chickens that are left is 4/7.
