Marri bought ½ pound licorice, ⅓ pound of candy worms, and 3/5 pound of jawbreakers. How many more pounds of jawbreakers than licorice did she buy?

To find the difference in pounds between the jawbreakers and licorice, we need to subtract the weight of the licorice from the weight of the jawbreakers.

Marri bought 3/5 pound of jawbreakers and 1/2 pound of licorice.

So the difference is 3/5 - 1/2.

To subtract these fractions, we need to find a common denominator. The lowest common denominator between 5 and 2 is 10.

So, we can rewrite the fractions with a common denominator: 3/5 = 6/10 and 1/2 = 5/10.

Now we can subtract: 6/10 - 5/10 = 1/10.

Therefore, Marri bought 1/10 pound more of jawbreakers than licorice.

The answer is 1/10 pound.
