(3/7)+N = (3/5)(13/21)(2/3)(5/14)7
(3 + 7N)/7 = (39/105)(10/42)7
(3 + 7N)/7 = (390/4,410)7
(3 + 7N)/7 = 2,730/4,410
13,230 + 30,870N = 19,110
30,870N = 5,880
N = 5,880/30,870
N = 1,176/6,174
N = 588/3,087
N = 196/1,029
(3 + 7N)/7 = (39/105)(10/42)7
(3 + 7N)/7 = (390/4,410)7
(3 + 7N)/7 = 2,730/4,410
13,230 + 30,870N = 19,110
30,870N = 5,880
N = 5,880/30,870
N = 1,176/6,174
N = 588/3,087
N = 196/1,029
