Question

The common house flea can grow up to a length of 5 millimeters (mm). About how many fleas could you lay end to end down the length of your textbook? Show work.

Answer 1

All you have to do is add an extra zero to the amount of centimeters your textbook is like for example, if your textbook is 10 cm add another zero and that would be 100 mm

Answer 2

Lets say the textbook’s length is 5 cm.

if each flea’s length is 5 mm then
5 cm = 50 millimetre
50 millimetre = 10 fleas!

The answer then will be ten fleas.
