Question

Помогите решить 1) -2,9:25+0,26)*(-100)= 2) (-12-3,7:(-0,4))*(-1,6)= 3) (-41:0,25+162,8):(-0,06)= 4) (-20,5)*(1821-73:0,04)=

Answer 1

(-2.9:25+0.26)*(-100)=0.114*(-100)=-14,4

Answer 2

1) (-2.9 / 25 + 0.26) * (-100) First, let's calculate the expression inside the parentheses: (-2.9 / 25 + 0.26) = -0.116 + 0.26 = 0.144 Now, multiply by -100: 0.144 * (-100) = -14.4

2) (-12 - 3.7 / (-0.4)) * (-1.6) First, let's calculate the expression inside the parentheses: (-12 - 3.7 / (-0.4)) = (-12 + 9.25) = -2.75 Now, multiply by -1.6: -2.75 * (-1.6) = 4.4

3) (-41 / 0.25 + 162.8) / (-0.06) First, let's calculate the expression inside the parentheses: (-41 / 0.25 + 162.8) = (-164 + 162.8) = -1.2 Now, divide by -0.06: -1.2 / (-0.06) = 20

4) (-20.5) * (1821 - 73 / 0.04) First, let's calculate the expression inside the parentheses: (1821 - 73 / 0.04) = (1821 - 1825) = -4 Now, multiply by -20.5: -4 * (-20.5) = 82

So, the solutions are: 1) -14.4 2) 4.4 3) 20 4) 82
