14 I Can…. determine if two ratios are equivalent.

15 Equivalent Ratios Essential Understanding: To create equivalent ratios, multiply or divide each quantity by the same number. To determine if two ratios are equivalent, first write the ratios in fraction form. Then find their cross products by multiplying the numerator of one ratio by the denominator of the other product. If the cross products are equivalent then the ratios are equivalent.
