4 over 7.
6/5 + 2/-9 = 44/45
It is: -2/5+6 = 5.6 or 5 and 3/5
8/-3 + -7/2 = 8x-2/-3x-2 + -7x3/2x3= -16/6 + -21/6= -37/6
It is: 1/2 or 0.5
4/8 + (-6) = 1/2 - 6 = -51/2
-2/9 + 5/6 = -4/18 + 15/18 = 11/18
z = -80
3 raised to negative 2 would be -9 plus 6 to the negative 1 which is -6 so -9+-6=-15
It should be negative 1 over z.
(6) + (-4) = 2
Negative 6.
4+(-6)=-2
