-884/70
(-884/2)/(70/2) (divide top & bottom by two)
-442/35
check - bottom can only be divided by 1, 5, and 7.
1 won't change anything.
top obviously cannot be divided by 5.
check if top can be divided by 7.
760 = 420
442 - 420 = 22
22 is not divisible by 7.
Therefore, 442 is not divisible by 7.
Therefore, -442/35 is simplest form.
