To find an equivalent ratio to the ratio of apples to oranges (which is 8 to 10), the correct method is:
B: Multiply or divide both sides of the ratio by the same number.
For example, if you divide both sides of the ratio 8:10 by 2, you get the equivalent ratio 4:5. Similarly, if you multiply both sides by 2, you get the equivalent ratio 16:20. In general, equivalent ratios maintain the same relationship between the two quantities.
