Answer 1

Ответ:

Пошаговое объяснение:

$1)-0,125*\frac{4}{9} =-\frac{125}{1000} *\frac{4}{9} =-\frac{125}{2250} =-\frac{1}{18}$

$2)-\frac{1}{18} *(-40)=-\frac{1}{18} *-\frac{40}{1} =\frac{20}{9}$

$3)\frac{20}{9} *(-1,8)=\frac{20}{9} *-\frac{18}{10} =-\frac{4}{1} =-4$

Answer 2

To calculate the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (left to right)
4. Addition and Subtraction (left to right)

Let's calculate the expression step-by-step:

-0.125 * 4/9 * (-40) * (-1.8)

Step 1: Evaluate parentheses first: -0.125 * 4/9 * 40 * 1.8

Step 2: Perform multiplication and division from left to right: -0.125 * (4/9) * 40 * 1.8

Step 3: Calculate the multiplication and division inside parentheses: -0.125 * (0.4444444444) * 40 * 1.8

Step 4: Continue with multiplication and division: -0.125 * 17.777777776 * 1.8

Step 5: Calculate the final result: -3.160493827 * 1.8

Step 6: Final multiplication: -5.6888888886

The result of the expression is approximately -5.6889.
