📚 Topic Summary
Ratio tables are a fantastic way to organize and find equivalent ratios. An equivalent ratio is simply a ratio that represents the same relationship as another ratio. Think of it like this: if you have a recipe that calls for 1 cup of flour for every 2 cups of water, that's a ratio. If you double the recipe, you'll need 2 cups of flour for every 4 cups of water. The ratio 1:2 is equivalent to the ratio 2:4. Ratio tables help you see these relationships clearly!
To complete a ratio table, you'll usually be given some starting values and need to find the missing ones. You can do this by multiplying or dividing both parts of the ratio by the same number. The key is to keep the relationship between the two parts of the ratio the same!
