m) (-0,45) : 1 4/5

n) (-2,75) : (-2,2) =

o) (-3,5) : (-1 2/5) =

Answer 1

B) 1 2/3 x (- 6/25)= 5/3 × (-6/25) = 1/1 × (-2/5) = -2/5
c) (-2 2/5) x (-3 3/4)= -12/5 × (-15/4) = -3/1 × (-3/1) = 9/1 = 9
d) (-9,45) x 0,28= -945/100 × 28/100 = -26460/10000 = -2,6460
e) 0,04 x (- 0,27)= 4/100 × (-27/100) = -108/10000 = - 0,0108
f) (-3,6) x 4/9= -36/10 × 4/9 = -4/5 × 2/1 = -8/5 = -16/10 = -1,6
g) (-2,1) x (-4 2/7)= -21/10 × (-30/7) = -3/1 × (-3/1) = 9/1 = 9
h)- 7/8 : (5,6)= -7/8 : 56/10 = -7/8 × 10/56 = -1/4 x 5/8 = -5/32

chyba będzi tak mam nadzieję
