Bob nailed wooden board sections to a fence. he nailed 2/9 of a section in 1/10 hour. explain how to use the information in the problem to find two different unit rates.

Your fractions are your units and rates.

A "section" is a unit and 2 of 9 sections is a rate.
An hour is a unit and 1 of 10 hours is a rate.

You can multiply the fractions and create a new unit rate that would measure a section per hour.
I hope this helps.

There should only be 1 solution
