Question

-0,025*(-0,45)*2/3*(-4000)=

Answer 1

-0,025*(-0,45)*2/3*(-4000)= -30

Answer 2

-0,025*-0,45=0,01125
1125/10000*2/3=2250/30000
2250/30000*-4000=900000/30000=30

Answer 3

To calculate the expression:

-0.025 * (-0.45) * 2 / 3 * (-4000)

You can follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In your expression, there are no parentheses or exponents, so we'll start with multiplication and division from left to right:

-0.025 * (-0.45) = 0.01125 0.01125 * 2 = 0.0225 0.0225 / 3 = 0.0075 0.0075 * (-4000) = -30

So, the result of the expression is -30.
