The ratios 124/344 and 109/124 both correctly describe the data in the table, but only the ratio 124/344 is a fraction. Why?

• A fraction should show a part-to-whole comparison.

• Fractions do not compare whole amounts.

• 124/344 is a ratio, but 344/124 is not.

• The top number of a ratio must always be less than the bottom number.
