Chapter SH, Problem 6.4.4EP

To determine

To find: Whether the set of numbers in each table is proportional or not.

Answer to Problem 6.4.4EP

The set of numbers in the table is non-proportional.

Explanation of Solution

Given information:

The table of the set of numbers:

  

The columns in the table represent the different rates of men’s shoe sizes to women’s show sizes.

Here, the rate in the first column can be written in proportion as: $\frac{6}{7.5}=0.8$

The rate in the second column can be written in proportion as: $\frac{6.5}{8}\approx 0.8125$

The rate in the third column can be written in proportion as: $\frac{7}{8.5}\approx 0.823$

The rate in the fourth column can be written in proportion as: $\frac{7.5}{9}\approx 0.8333$

It is seen that each proportion is notequal to each other.

Hence, the set of numbers in the table is non-proportional.
