The set of numbers in the table is proportional.

Explanation of Solution

Given information:

The table of the set of numbers:

  

The columns in the table represent the different rates of cups of flour to cups to sugar.

Here, the rate in the first column can be written in proportion as: $\frac{2}{1.5}\approx 1.333$

The rate in the second column can be written in proportion as: $\frac{4}{3}\approx 1.333$

The rate in the third column can be written in proportion as: $\frac{6}{4.5}\approx 1.333$

The rate in the fourth column can be written in proportion as: $\frac{8}{6}\approx 1.333$

It is seen that each proportion isequal to each other.

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