Several students were asked to name the kinds of animals they saw in the past week at the park. Determine the ratio that compare

SVETLANKA909090 [29]

Answer:

A. 1:8

Step-by-step explanation:

We have been given that several students were asked to name the kinds of animals they saw in the past week at the park.

Dogs: 8

Cat: 2

Fish: 4

Lizard: 2

We are asked to find the ratio that compares the number of cats seen to the total number of animals seen.

Let us find total number of animal by adding each type of animals as:

$\text{Total animals}=8+2+4+2$

$\text{Total animals}=16$

We can see that the students saw 2 cats, so ratio of cats to total animals would be $2:16$ .

Dividing 2 and 16 by 2, we will get:

$\frac{2}{2}:\frac{16}{2}\Rightarrow 1:8$

Therefore, the ratio 1:8 compares the number of cats seen to the total number of animals seen and option A is the correct choice.
