(30%)(120%)(40%)N = (60%)(80%)(30) (30/100)(120/100)(40/100)N = (60/100)(80/100)(30) (3/10)(6/5)(2/5)N = (3/5)(4/5)(30) (36/250)N = (360/25) 36N/250 = 360/25 900N = 90,000 N = 90,000/900 N = 900/9 N = 100
(30/100)(120/100)(40/100)N = (60/100)(80/100)(30)
(3/10)(6/5)(2/5)N = (3/5)(4/5)(30)
(36/250)N = (360/25)
36N/250 = 360/25
900N = 90,000
N = 90,000/900
N = 900/9
N = 100
