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 :

In this question, you are asked to find the ratio of two things that represented with fraction number. Then, it will be easier to change the denominator of them both to the same number. The least common multiple of 9(3x3) and 15(3x5) will be 45(3x3x5). Then the size would be:

Ring         : 5/9 x 5/5= 25/45
Earring     : 4/15 x 3/3= 12/45

Then the ratio of ring/earring would be 25/12 = 2.083 times
