Staff Review
This lesson talks about writing many different ratios as fractions and reducing them to simplest terms. Ratios include decimals and fractions, and some get pretty complicated. This is a great tutorial for becoming fluent with decimals and fractions. -

Does not explain what a ratio is. Does not explain the difference between a ration and a fraction. Very disturbing and annoying presentation - probably the worst i've seen.
