Answer 1

a) (-25/3)+(-8/5)+19/2 =
(-250-54+285) / 30 =
-19/30
b) (-3/10)-(-4/15)+13/4=
(-3/10)+ (4/15) + 13/4 =
(-18+16+195) / 60 =
193/60
c) 15-(-1/9)-17/2=
15+1/8-17/2=
(-270 + 2 - 153)/18=
-421/18
d) (-2/9)-(-16/3)-19/6=
(-2/9)+(16/3) - 19/6 =
(-4+96-57)/18=
35/18
e) -7/20-5-1/4=
(-7-100-5)/20
-112/20= -28/5
