Question

In a jewelry store, rings make up 5/9 of the inventory. Earrings make up 4/15 of the inventory. How many times greater is the ring inventory than the earring inventory?

Answer 1

Make the fractions have common denominators.

rings 5 / 9 * 5/5 = 25/45
earrings 5/15 * 3/3 = 15/45

So, now we can compare 25 to 15.  25 is 5/3 bigger than 15.
or the ring inventory is 1.666666666... times greater than the earring inventory.
