How do you determine if two ratios are equivalent?

Back

Two ratios are equivalent if they represent the same relationship between quantities. This can be checked by cross-multiplying. For example, to check if 4 : 5 and 8 : 10 are equivalent, calculate 4 * 10 and 5 * 8. Both equal 40, so the ratios are equivalent.
