Answer: To find how much greater the beetle's length is than its width, we need to subtract the width from the length:
Length - Width
Substituting the given values, we get:
2/5 inch - 1/5 inch
Simplifying the expression by finding the common denominator of 5, we get:
(2/5 - 1/5) inch
= 1/5 inch
Therefore, the beetle's length is 1/5 inch greater than its width.
