PROSZE O POMOC!!! PLIS NA JUTRO!!!!

Answer 1

A)-1 1/4 razy (-4)=-5/4*(-4)=5
b)-6 2/3 : 2= -20/3 *1/2=-10/3
c) -0,2 razy (-2)=0,4
d) -3 1/3 razy (-3)= -10/3*(-3)=10
e) (-3)^2 razy 1/3=9*1/3=3
f) (1/3)^2 razy (-9)=1/9*(-9)=-1
g) -6^2 :1/2=-36*2=-72
h) 3 3/4 : (-1,25)^2=15/4:25/16=15/4*16/25=12/5

Answer 2

a)-1 1/4 razy (-4)= -5/4*(-4)= -(-5/4*4)= -(-5)=5
b)-6 2/3 : 2= -20/3:2= -10/3= -3 1/3
c) -0,2 razy (-2)= -(-0,2*2)= -(-0,4)=0,4
d) -3 1/3 razy (-3)= -10/3*(-3)= -(-10/3*3)= -(-10)=10
e) (-3)^2 razy 1/3=9*1/3=3
f) (1/3)^2 razy (-9)=1/9*(-9)= -1/9*9= -1
g) -6^2 :1/2= -36:1/2= -72
h) 3 3/4 : (-1,25)^2=15/4:(-1,25)^2=3,75:25/16=2,4
