Marri bought 1/2
pound licorice, 1/3
pound of candy worms, and 2/5
pound of jawbreakers. How many more pounds of jawbreakers than licorice did she buy?
To find out how many more pounds of jawbreakers Marri bought than licorice, we need to subtract the weight of the licorice from the weight of the jawbreakers.
The weight of the licorice is 1/2 pound.
The weight of the jawbreakers is 2/5 pound.
To subtract the two weights, we need a common denominator. The least common multiple of 2 and 5 is 10.
Converting the fractions to have a denominator of 10:
1/2 pound = 5/10 pound
2/5 pound = 4/10 pound
Subtracting the weights:
4/10 pound - 5/10 pound = -1/10 pound
Therefore, Marri bought 1/10 pound less of jawbreakers than licorice.
