Question

There are 40 cows and 15 chickens. Compare the number of chicken to the total number of animals. Write the answer in three ways.

Answer 1

Answer:

0. The ratio of the Number of Chickens to the total number of animals = 15:55

,

1. We can then say that for every 11 animals, 3 are chickens.

,

2. Chickens are 27% of the total population of animals.

Explanation:

Number of Cows =40

Number of chickens = 15

Total = 40+15=55

• The ratio of the Number of Chickens to the total number of animals = 15:55

If we divide both sides by 5, we have

$\begin{gathered} \frac{15}{5}\colon\frac{55}{5} \\ =3\colon11 \end{gathered}$

• We can then say that for every 11 animals, 3 are chickens.

We can also express it as a percentage.

$\begin{gathered} \%\text{ of ch.i}ckens\text{ =}\frac{15}{55}\times100 \\ =27\% \end{gathered}$

• Chickens are 27% of the total population of the animals.
