Question

please simplify and show all works,perform indicated operation

-24/55   dived by 39/40

Answer 1

(-24/55) / (39/40)

(-24/55) * (40/39)

(-24 * 40) / (55 * 39)

cancel a 3 from the 24 and 39:

(-8 * 40) / (55 * 13)

cancel a 5 from the 40 and 55:

(-8 * 8) / (11 * 13)

11 and 13 are prime and there are no 11s or 13s on top, so we can't reduce any further

-64 / 143
