Answer: 1/8 of a pound

Step-by-step 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, which is 3/4. 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

(The * means multiplication)

Answer:

1/8 of a pound

Step-by-step explanation:

Gina's bag of gumdrops : 1/4 of a pound

Gina's + sister's bag of gumdrops : 3/8 of a pound

To find how much her sister's gumdrops weighed, you will have to subtract fractions.

Equation : 3/8 - 1/4 or 3/8 - 2/8

To subtract, you need to make sure the denominators are the same.

1 × 2

-------  =  2/8

4 × 2

Now, you can subtract. Subtract the numerators.

3/8 - 2/8 = 1/8

So, Gina's sister's red gumdrops weigh 1/8 of a pound.
