Answer:
41/60
Step-by-step explanation:
Convert the fractions into like denominators: 7/30 = 140/600, 9/20 = 270/600

Divide into a smaller fraction: 41/60
Step One
Find the Volume in ccs.
V= l*w*h
l =40 mm
w = 25 mm
h = 2 mm
V = 40*35 * 2
V = 2800 mm^3
Step Two
Find the weight
1 mm^3 = 0.0005
2800 mm^3 = x <<<<< answer 1

Cross multiply.
1x = 2800 * 0.0005
x = 1.4 ounces. <<<<< answer 2
The answer is C and its because they are the farthest apart from each other.
