To simplify the expression \( (1.1 - 0.3) \div 8 + 4 \times 3 \), we will follow the order of operations (parentheses, exponents, multiplication and division from left to right, addition and subtraction from left to right).
-
First, simplify the parentheses: \[ 1.1 - 0.3 = 0.8 \] Now the expression is: \[ 0.8 \div 8 + 4 \times 3 \]
-
Next, perform the division: \[ 0.8 \div 8 = 0.1 \] So now we have: \[ 0.1 + 4 \times 3 \]
-
Now, perform the multiplication: \[ 4 \times 3 = 12 \] The expression is now: \[ 0.1 + 12 \]
-
Finally, add the two results: \[ 0.1 + 12 = 12.1 \]
Therefore, the simplified result is \( \boxed{12.1} \).
