To find out how much more licorice Gabriel bought than candy worms, we first need to find the quantities of licorice and candy worms that he bought.
Since we know that Gabriel bought 7/15 pound licorice, 1/3 pound candy worms, and 3/5 pound jawbreakers, we can add these fractions together:
7/15 + 1/3 = 21/45 + 15/45 = 36/45
Simplifying this fraction, we get:
36/45 = 4/5 pound
So Gabriel bought 4/5 pound of licorice.
Now we need to find out how much candy worms he bought. We already know it's 1/3 pound.
Therefore, Gabriel bought 4/5 - 1/3 pounds of licorice more than candy worms.
To subtract these fractions, we need to have a common denominator. The least common multiple of 3 and 5 is 15.
Multiplying 4/5 by 3/3 (which is the same as multiplying by 1) to get a common denominator:
4/5 * 3/3 = 12/15
So Gabriel bought 12/15 pound of licorice more than candy worms.
As a simplified fraction, this would be:
12/15 = 4/5 pound
Therefore, Gabriel bought 4/5 pound more of licorice than candy worms.
