Understanding Ratios and Fractions

The video tutorial explains ratio notation, emphasizing the importance of order in writing ratios. It distinguishes between part-to-part and part-to-whole ratios, using fractions as an example of the latter. Through examples, it demonstrates how to calculate and interpret ratios and fractions, including a problem involving donuts and another involving students and tables in a classroom. The tutorial highlights different ways to represent the same scenario with ratios, showing that both simplified and total representations can be correct.

What is a key aspect to remember when writing ratios?

• The order of terms is crucial.

• Ratios must always be simplified.

• Ratios should always be written as fractions.

• The order of terms is not important.
