Hej. potrzebuje na teraz ! Oblicz iloczyny: 5/7*2 i 1/3= (-16)*(-5/12)= (-3/4)8(-8/9)= (-0,7)*(-2,43)= -1/2*(-3/4)*(-2)*4= (-5/6)*(-2,5)*(-12/5)= 0,4*7/5*(-10)*(-5/12)*(-1)= (-5,4)*(-0,2)*100*(-1-27)*1/4= 8*(-6)*1/4*1/6= (-2,5)*1/2*(-4)= 2 i 2/5*(-7 i 1/2)= 12.4*(-0,5)= (-50)*8= (-4 i 1/4)*1 i 3/17=

Answer 1

5/7*2 i 1/3= 5/7 * 7/3 = 5/3 = 1 2/3

(-16)*(-5/12)= (-4)*(-5/3) = 20/3 = 6 2/3

(-3/4)*(-8/9)= (-1)*(-2/3) = 2/3

(-0,7)*(-2,43)= 1,701

-1/2*(-3/4)*(-2)*4= 3/8*(-2)*4 = (-6/8)*4 = -24/8 = -3

(-5/6)*(-2,5)*(-12/5)= (-5/6)*(-5/2)*(-12/5) = 25/12*(-12/5) = -5

0,4*7/5*(-10)*(-5/12)*(-1)= 2/5*7/5*(-10)*(-5/12)*(-1) = 14/24*(-10)*(-5/12)*(-1) = (-140/24)*(-5/12)*(-1) = (-35/24)*(-5/3)*(-1) = 175/72*(-1) = -175/72 = -2 31/72

(-5,4)*(-0,2)*100*(-1-27)*1/4= 1,08*100*0,25 = 108*0,25 = 27

8*(-6)*1/4*1/6= (-48)*1/4*1/6 = -12*1/6 = -2

(-2,5)*1/2*(-4)= (-2,5)*0,5*(-4) = (-1,25)*(-4) = 5

2 i 2/5*(-7 i 1/2)= 12/5*(-15/2) = 6*(-3) = 18

12.4*(-0,5)= -6,2

(-50)*8= -400

(-4 i 1/4)*1 i 3/17= (-17/4)*20/17 = (-1)*5 = -5
