68 paramecia are found in an area measuring 2 cm x 3 cm. _____ paramecia/cm2 *
Vladimir79 [104]
So the area is 2x3 cm with 68 paramecia.

Not sure if this is the best way to do it, but I’d do 68/2*3 (68 divided by (2 times 3))

So first 2*3 is 6cm.

Now you’re trying to find paramecia/cm2. You are trying to find a unit rate. That is a value over one.

Then because there are 68p and 6cm, to find the unit rate, you’d do 68/6.

Now you have your unit rate, which is 11.3 repeating, or 11 1/3 as a fraction.

That would be 11.3 (11 1/3) paramecia per cm2

also I’m not 100% sure if this is correct, just wanted to help, so no guarantees

The measure of randomness or disorder in a system is known as entropy

Entropy is the property of the system and it is also often regarded to be the measure of molecular randomness or disorder in a closed but changing system. The higher the entropy of a system, the higher the disorder and the higher the unavailability of the system's energy to perform useful work.
