Two sixth grade science classes are making salt water solutions. The first class (Class A) is using a ratio of three parts salt to five parts water. The other class (Class B) is using a ratio of two parts salt to four parts water. Make an equivalent ratio table for each class to represent its solution. Each table should show at least three equivalent ratios. Make sure to indicate which ratio table belongs to which class.
