Question

А) 2 1\3 + 1,2 = б)3\4 - 0,5= -1 2\5*2,3= (-0.8) : (-2 2.3) = Пожалуйста!

Answer 1

А) 8.2
Б) -0.25
В) -5.52
Г) не делится

Answer 2

а) 2 1/3 + 1.2 = 2.333... + 1.2 = 3.533...

б) 3/4 - 0.5 = 0.75 - 0.5 = 0.25

-1 2/5 * 2.3 = -1.4 * 2.3 = -3.22

(-0.8) : (-2 2.3) = 0.8 / 2.3 = 0.3478... (rounded to four decimal places)

Therefore: а) 2 1\3 + 1,2 = 3.533... б)3\4 - 0,5= 0.25 -1 2\5*2,3= -3.22 (-0.8) : (-2 2.3) = 0.3478...
