Lesson Objective We can use ratios to compare two quantities Math real world video ratio and rates: https://my.hrw.com/content/hmof/math/gomath/common/video/video.html#videoId=ref:TXGOMTH_RW_V6.08

Ratios Ratio – a comparison of two quantities

Example: What is the ratio of Science Fiction to Cartoons? Ratios Example: What is the ratio of Science Fiction to Cartoons? Ratios are written in three different ways: Written form 1 to 2 Colon form 1:2 Fraction form ½

Ratios There are two types of ratios: part to part part to whole

Ratios Equivalent ratios are ratios that name the same comparison. You can find equivalent ratios by using a table or by multiplying or dividing both terms of a ratio by the same number. What is the ratio of cartoons to total number of videos?

Ratios Equivalent ratios are ratios that name the same comparison. You can find equivalent ratios by using a table or by multiplying or dividing both terms of a ratio by the same number. What is the ratio of cartoons to total number of videos? 2/14 2 to 14 2:14 Another way to write 2:14 is 1:7 because 2:14 can be simplified to 1:7
