Question

I need help and show the work?

Answer 1

The difference is the answer to a subtraction problem. 

Subtract the smaller insect (1.33) from the bigger insect (2.01), which would end up looking like this: 

2.01 cm 
-1.33 cm 
-------- 
0.68 cm 

So, the difference of the subtraction problem is 0.68 cm.
