Awesome lesson. I love the cross-canceling you used to make converting units a lot simpler to solve. :)

HI,

Where can I get more practice examples and exercises on converting units and unit rates and ratios?

Thank you. :)

I read about converting units as explained in this video a long time ago in a Saxon math textbook but never really understood how to do it. This video really clears everything up for me. Now I can do this without any hesitation or confusion. Thanks.

How would I solve this problem...A chain saw requires a mixture of 2-cycle engine oil and gasoline. According to the

directions on a bottle of Oregon 2-cycle Engine Oil, 2.5 fluid ounces of oil are required for

1 gallon of gasoline. For 2.75 gallons, how many fluid ounces of oil are required?
