K) (-2 i 2/3) ÷ 1,2 = -8/3 : 6/5 = -8/3 * 5/6 = -40/18 = -20/9 = -2 2/9
L) 2/3 ÷ (-6) = 2/3 * (-1/6) = -2/18 = -1/9
M) (-0,45) ÷ 1 i 4/5 = -0,45 : 1,8 = -4,5 : 18 = -45 : 180 = -45/180 =
= -15/60 = -1/4
N) (-2,75) ÷ (-2,2) = 27,5 : 22 = 275 : 220 = 275/220 = 55/44 = 5/4 = 1,25
O) (-3,5) ÷ (1 i 2/5) = -3,5 : 1,4 = -35 : 14 = -35/14 = -5/2 = -2,5

Odpowiedź:
Szczegółowe wyjaśnienie:
(-2 2/3)÷ 1,2= -8/3:12/10= -8/3* 10/12= -20/9= -2 2/9
2/3 ÷ (-6)=2/3*(-1/6)= -2/18= -1/9
(-0,45) ÷ 1 4/5=45/100:9/5=9/20 *5/9=1/4
(-2,75) ÷ (-2,2)= -275/100: (-22/20)=-275/100* (-20/22)= 275/110=2 5/10=2,5
(-3,5) ÷ 1 2/5=-35/10 :7/5= -35/10*5/7= -25/20=-2,5
