2,66:3,8-0,81•0,12+0,0372

Answer

To solve the expression \(2.66:3.8 - 0.81 \cdot 0.12 + 0.0372\), we will follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

Division: \(2.66 \div 3.8\) \[ 2.66 \div 3.8 \approx 0.699 \]
Multiplication: \(0.81 \cdot 0.12\) \[ 0.81 \cdot 0.12 = 0.0972 \]
Now substitute back into the expression: \[ 0.699 - 0.0972 + 0.0372 \]
Subtraction: \[ 0.699 - 0.0972 = 0.6018 \]
Addition: \[ 0.6018 + 0.0372 = 0.639 \]

So, the final result is approximately \(0.639\).

2,66:3,8-0,81•0,12+0,0372

Answer

To solve the expression \(2.66:3.8 - 0.81 \cdot 0.12 + 0.0372\), we will follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). 1. **Division:** \(2.66 \div 3.8\) \[ 2.66 \div 3.8 \approx 0.699 \] 2. **Multiplication:** \(0.81 \cdot 0.12\) \[ 0.81 \cdot 0.12 = 0.0972 \] 3. **Now substitute back into the expression:** \[ 0.699 - 0.0972 + 0.0372 \] 4. **Subtraction:** \[ 0.699 - 0.0972 = 0.6018 \] 5. **Addition:** \[ 0.6018 + 0.0372 = 0.639 \] So, the final result is approximately \(0.639\).
