Chapter 7.2, Problem 9CYU

To determine

Find type of pet that owned mostly by the students in Miss Han’s class.

Answer to Problem 9CYU

In Miss Han’s class, most of the students own a dog.

Explanation of Solution

Given:

Cat owner = 32%

Dog owner = $\frac{3}{8}$

  $\frac{3}{8}$

Bird owner = 0.29

Calculations:

Here, we have to compare pet owners in percent form.

We have 32% cat owner.

Now expressing dog owners in percent form,

  $\begin{array}{l}\frac{3}{8}=\frac{3}{8}\times 100\\ =37.5\%\end{array}$

Expressing bird owners in percent form,

  $\begin{array}{l}0.29=0.29\times 100\\ =29\%\end{array}$

Comparing pet owners, we get

  $37.5\%>32\%>29\%$

Dog owner > cat owner > bird owner

Conclusion:

Therefore, most of the students in Miss Han’s class own a dog.
