Doubling the side-lengths will multiply the area by four.
Proof:
Let the side-lengths of the rectangle by x and y. Clearly, the area will be x*y=xy. The new rectangle will have side-lengths 2x and 2y, and thus area 2x*2y=4xy. 4xy/xy=4 - hence, the new rectangle has four times the area of the old one.
In order to do this, we multiply both sides be the amount that would make the left side equal to 1. This number is the reciprocal of the fraction, so we multiply both sides by 3/2. This is equal to:
w = 9/8
So, the blueberries in crystal's basket will weigh 9/8 pounds when it is full.

Answer:
The sum is close to 1/2
Step-by-step explanation:
1/4 = 7/28
2/7 = 8/28
7/28 + 8/28 = 15/28
14/28 = 1/2 and 15/28 is close to 14/28
