EXAMPLE 2 Using the Cross Products Property 6.8 15.4 = 40.8 m Write original proportion. Cross products property Multiply. 6.8m 6.8 = 628.32 6.8 Divide each side by 6.8. m = 92.4 Simplify. Check: You can check your solution by finding the cross products of the proportion. If the cross products are equal, the solution is correct. 6.8m = 15.4 (40.8) 6.8m = 628.32

2
EXAMPLE 2 Substitute 92.4 for m. Multiply. 6.8 (92.4) 15.4 (40.8) = ? 628.32 628.32 = ? 6.8 15.4 = 40.8 92.4 Using the Cross Products Property
