Chapter 6.3, Problem 32E

To determine

To find if the two ratios are equivalent

Answer to Problem 32E

The small packing size is selling milk at rate of $0.225 while the bigger packing size is selling milk at rate of $0.2 so the two rates are not equivalent as The bigger packing size is selling the milk at a lower rate than the smaller packing size

Explanation of Solution

Given information :

Considerthe question that can buy 10 ounces for $2.25 or can buy 35 ounces for $7bike can travel 24 miles in 2 hour

Calculations:

Assume the smaller packing as $\text{x}$ and the bigger packing be $\text{y}$

First have to find the rate of one ounce of milk in both the packing individually,

Therefore,

The rate becomes;

  $\begin{array}{l}\text{x = }\frac{2.25}{10}\\ \text{ =0}\text{.225 }\\ \end{array}$

So the rate of one ounce of milk in smaller packing is $0.225

  $\begin{array}{l}\text{y = }\frac{7}{35}\\ \text{ =0}\text{.2}\end{array}$

And the rate of one ounce of milk in bigger packing is $0.2

Therefore,The small packing size is selling milk at rate of $0.225 while the bigger packing size is selling milk at rate of $0.2 so the two rates are not equivalent as The bigger packing size is selling the milk at a lower rate than the smaller packing size expression will be 60miles
