a)
3/4 - 1 9/16 = 12/16 - 1 9/16 = 12/16 - 25/16 = -13/16
b)
4 4/3 * (-2 5/8) - 1 1/2 = 16/3 * (-21/8) - 1 1/2 = -14 - 1 1/2 = -15 1/2
c)
2 : (-2 2/3) + 3 3/4 : 2 - 3 = 2 : (-8/3) + 15/4 * 1/2 - 3 = -2 * 3/8 + 15/8 - 3 =
= -3/4 + 1 7/8 - 3 = -6/8 + 1 7/8 - 3 = 1 1/8 - 3 = -1 7/8
d)
[1 1/6 : (-3) - 1/3] * (-2/5) = (-7/6 * 1/3 - 1/3) * (-2/5) = (-7/18 - 1/3) * (-2/5) =
= (-7/18 - 6/18) * (-2/5) = 13/18 * 2/5 = 13/9 * 1/5 = 13/45
