To determine which of the tables follows a ratio, we should look for a relationship between the values in columns A and B. A ratio means that for every unit increase in column A, the corresponding value in column B increases in a consistent proportion.

Let's analyze the tables one by one:

  1. First Table:

    A B
    1 5
    2 6
    3 7
    

    The differences in column B are 1 (from 5 to 6 and from 6 to 7). This does not show a consistent ratio.

  2. Second Table:

    A B
    1 1
    2 4
    3 9
    

    The differences in column B are 3 (from 1 to 4) and 5 (from 4 to 9), which also does not show a consistent ratio.

  3. Third Table:

    A B
    1 4
    2 5
    3 7
    

    The differences are +1 (from 4 to 5) and +2 (from 5 to 7), again showing no constant ratio.

  4. Fourth Table:

    A B
    1 2
    2 4
    3 6
    

    The differences are +2 (from 2 to 4) and +2 (from 4 to 6). This shows a consistent increase, and we can see that B = 2A. Thus, this table follows a strict ratio of 2:1.

Based on the analysis above, the fourth table follows a ratio (specifically 2:1).
