Answer:
5/8 of a pound
Explanation:
Jake's amount of gumdrops is 1/8 of a pound, and the sum of Jake's amount and his sister's amount is 3/4 of a pound. Let's call the amount of gumdrops his sister got by X.
So, we have that:
(1/8) + X = 3/4
(1 + 8*X)/8 = 6/8
1 + 8*X = 6
8*X = 5
X = 5/8
The weight of his sister's amount of gumdrops is 5/8 of a pound
