Математика: (-5,8+3,,2)-3,04 -6,03*2,,,05) 7/18(1 4// 1/6) (-1 7/8* 1 4/5+9//9)

алина677323 · Answer

(-5,8+3,6)(-1,2)-3,04=-2,2×(-1,2)-3,04=2,64-3,04=-0,4
-6,03*2,1-(-0,14)(-0,05)=-12,663-0,007=-12,67
7/18(1 4/7)-(-4/21)(-1 1/6)=7/18×11/7-4/21×7/6=11/18-2/9=11/18-4/18=7/18
(-1 7/8* 1 4/5+9/16)(-8/9)=(-15/8×9/5+9/16)(-8/9)=(-27/8+9/16)(-8/9)=(-54/16+9/16)(-8/9)=(-45/16)(-8/9)=5/2=2,5
