How do you know if your answer for a proportion problem is correct?

Answer 1

To verify if your answer for a proportion problem is correct, check if the cross products are equal. For example, in a proportion of the form ( \frac{a}{b} = \frac{c}{d} ), ensure that ( a \times d = b \times c ). Additionally, review your calculations for any arithmetic errors and confirm that your final answer makes sense in the context of the problem. Lastly, you can also substitute your answer back into the original problem to see if it holds true.
