Ratios & Equivalent Ratios

How can you check if two ratios are equivalent?

• Add the ratios together; if the sum is the same, the ratios are equivalent.

• Cross-multiply the ratios; if the products are equal, the ratios are equivalent.

• Divide the first ratio by the second; if the result is 1, the ratios are equivalent.

• Subtract the smaller ratio from the larger; if the difference is 0, the ratios are equivalent.
