Find the following rates. Round your answer to the nearest hundredth. a. ? % of 75 = 5 b. ? % of 28 = 140 c. ? % of 100 = 40 d. ? % of 200 = 15

Answer:a) 6.67% b) 500% c) 40% d) 7.5%Step-by-step explanation:a. ? % of 75 = 5Let ? be y.Of means multiply so we will replace it with a multiplication sign.y% x 75 = 5y% = 5/75y% = 1/15 x 100y = 6.67 %b) ?% of 28 = 140Let ? be y.Of means multiply so we will replace it with a multiplication sign.y% x 28 = 140y% = 140/28y% = 5y = 5 x 100y = 500%c) ?% of 100 = 40Let ? be y.Of means multiply so we will replace it with a multiplication sign.y% x 100 = 40y% = 40/100y% = 2/5y = 2/5 x 100y = 40%d) ?% of 200 = 15Let ? be y.Of means multiply so we will replace it with a multiplication sign.y% x 200 = 15y% = 15/200y% = 3/40y = 3/40 x 100y = 7.5 %!!
