Answer :
Based on the information provided in the table, the equivalent ratios are:
1. B:A = 1:5
2. B:A = 2:10
3. B:A = 3:15
4. B:A = 9:45
These ratios are equivalent because the values in the two columns maintain the same proportional relationship. For example, in the first row, the value of B is 1 and the value of A is 5, so the ratio of B to A is 1:5.
The key properties of equivalent ratios are:
1. The ratios have the same proportional relationship between the values in the two columns.
2. The values in the two columns are directly proportional to each other.
3. The ratios can be expressed as fractions that are equal to each other.
In this case, the ratios presented in the table are equivalent because they all have the same proportional relationship between the values in the B and A columns.
