Answer:
The fraction will increase by 100%
Step-by-step explanation:
Say the fraction is x/y. The question is telling us to decrease x by 20% (i.e. 0.8x) and to decrease y by 60% (i.e. 0.4y):

You can see that by applying these changes, the new fraction is actually double the old fraction (i.e. will increase by 100%).
The volume of the rectangular prism is 3359232 cubic centimeters
<h3>How to determine the volume?</h3>
The length of the cube is given as:
Length, l = 12 cm
The volume of a cube is:

So, we have:

Evaluate
V = 1728
The volume of 1944 cubes is then calculated as:
Volume = 1728 * 1944
Evaluate
Volume = 3359232
Hence, the volume of the rectangular prism is 3359232 cubic centimeters
