Question

-2.8:(1.6-1.2)+3.4 1.7*(-4)-1.6*5 0.8-1.5*14+2.3 (-1.9-0.3):(-2.6+3.1) 3.6-2.3*(0.73-0.37)

Answer 1

-2.8:(1.6-1.2)+3.4 = -2.8:0,4+3,4=-7+3,4= -3,6
1.7*(-4)-1.6*5 = -6,8 - 8= -14,8
0.8-1.5*14+2.3 = 0,8-21+2,3=-17,9
(-1.9-0.3):(-2.6+3.1) = -2,2 : 0,5= -4,4
3.6-2.3*(0.73-0.37) = 3,6 - 2,3*0,36=3,6-0,828= 2,772
