Answer:
inches.
Step-by-step explanation:
We have been given that a praying mantis at the right is 10.5 centimeters long. We are asked to represent the given length as a mixed number.
We know that a mixed number consists an integer and a fraction. We can represent our given number as:
Therefore, the mixed number represents the given length.
