Description From Ratio Tables to Double Number Lines
After this lesson, you will be able to transform ratio tables into double number line diagrams.
The lesson begins by teaching you that equivalent ratios can be presented in a ratio table. It leads you to learn how to rewrite the entries in a ratio table horizontally to produce a double number line diagram. It concludes with a hint that double number line diagrams are more visually-friendly when comparing ratios.
