Answer 1

changes to top-heavy impropers:

-28,345,967/4620 + 68,593,307/6930 - 8,262,883/2310

factors out 1/2310

1/2310 * (-28,345,967/2 + 68,593,307/3 - 8,262,883)

common denominator is 6:

1/2310 * ( -85,037,901 + 137,186,614 - 49,577,298)/6

1/2310 * 2,571,415/6 =

2571415/13860 =

185 + 7315/13860
