Question

Based on the data, which table shows a proportional relationship?


4 tables with 2-columns and 3 rows. Column 1 is labeled Oranges and Column 2 is labeled Cups of Juice. Table A has column 1 entries 3, 4, 5. Column 2 entries are 1, 2, 3. Table B has column 1 entries 3, 6, 9. Column 2 entries are 1, 2, 3. Table C has column 1 entries 3, 3, 3. Column 2 entries are 1, 2, 3. Table D has column 1 entries 3, 5, 7. Column 2 entries are 1, 2, 3.

Answer 1

Table B.

Each pair in B (3,1), (6,2), (9,3) has the same ratio cups/oranges = 1/3 (or oranges = 3 × cups), so cups and oranges are proportional. The other tables do not have a constant ratio.
