To simplify the expression \( (1.9 - 0.3) \div 8 + 4 \times 3 \), we will follow the order of operations (PEMDAS/BODMAS):
-
Parentheses/Brackets: First, we simplify the expression inside the parentheses: \[ 1.9 - 0.3 = 1.6 \] Now the expression becomes: \[ 1.6 \div 8 + 4 \times 3 \]
-
Division and Multiplication: Next, we perform the division and multiplication from left to right:
- First, we do the division: \[ 1.6 \div 8 = 0.2 \]
- Then, we do the multiplication: \[ 4 \times 3 = 12 \]
-
Addition: Now we combine the results from the division and multiplication: \[ 0.2 + 12 = 12.2 \]
Therefore, the simplified expression is: \[ \boxed{12.2} \]
