What is a ratio? A ratio is just a comparison of two numbers or values, expressed in the same terms or units. In other words, in ratios we always compare dollars to dollars, pounds to pounds, hours to hours, and so on. A ratio can be written in words, with a colon, or as a fraction. Ratios are always written in reduced form. Ex: 2 apples you eat to 3 apples I eat Ratio: 2 to 3, 2:3, 2/3 Answer the following: 1. Can you compare two different units such as minutes to hours with rations? ___ 2. What are the three ways you can write the following as a ratio 1 hour of homework to 1 hour on the phone? _______________________________________
