Answer:
(-1)/28
Step-by-step explanation:
Simplify the following:
((-19)/2×1/38)/7
(-19)/2×1/38 = (-19)/(2×38):
((-19)/(2×38))/7
(-19)/(2×38)×1/7 = (-19)/(2×38×7):
(-19)/(2×38×7)
The gcd of -19 and 38 is 19, so (-19)/(2×38×7) = (19 (-1))/(2 (19×2) 7) = 19/19×(-1)/(2×2×7) = (-1)/(2×2×7):
(-1)/(2×2×7)
2×2 = 4:
(-1)/(4×7)
4×7 = 28:
