Odpowiedź:
a)
3/7*(-4)= -12/7 = -1 5/7
b)
-4/5:(-10/11)= -4/5 * (-11/10) = 2/5 * 11/5 = 22/25
C)
-7/12:6/14= -7/12 * 14/6 = -7/6 * 7/6 = -49/36 = -13/36
d)
-2 1/4*(-4/9) = -9/4 * (-4/9) = 1
e)
-3:5 1/3= -3 : 16/3 = -3 * 3/16 = -9/16
f)
-2 1/5*(-3 1/7)= 11/5 * 22/7 = 242/35 = 6 32/35
g)
-3 1/8 : (-6 3/8) = 25/8 : 51/8 = 25/8 * 8/51 = 25/51
