A ratio is the relationship between two amounts. A ratio can be expressed as a fraction. What comes to mind is icing cupcakes. If I use one cup of vanilla cake icing to ice 4 cupcakes, and one cup of chocolate icing to ice 2 cup cakes, which cup cakes have more icing on them, […]

This explains why kids can sing every word of a song they like but have a difficult time learning information for a math or science test.
