Question

(1 1/3*0,27-3 1/3*0,15) - 1500*(0,1)в кубе

Answer 1

1 1/3×0.27=4/3×27/100=9/25
3 1/3×0.15=10/3×3/20=1/2
9/25-1/2=18/50-25/50=-7/50
0.1^3=0.001
1500×0.001=1.5=1 1/2=3/2
-7/50-3/2=-7/50-75/50=-82/50=
=-41/25=-1 16/25

Answer 2

11/3 х27/100-31/3х15/100-1500х0,001=
=99/100-155/100-1,5=-56/100-1,5= -56/100-150/100=-206/100=-2,06
