Let (L) equal the time in minutes to solve 50 math problems. First ratio: 30 problems/ 45minutes. Second ratio: 50 problems/LMake sure the second ratio is setup with problems over minutes. Set each ratio equal. 30/45=50/L To solve proportions cross-multiply the ratios. 30L = 45(50) to solve for L divide both sides by 30. L = 75 minutes to solve 50 problems.
