To simplify the expression \( (1.1 - 0.3) \div 8 + 4 \times 3 \), we follow the order of operations (parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right).
-
Calculate the parentheses: \[ 1.1 - 0.3 = 0.8 \] Now the expression is: \[ 0.8 \div 8 + 4 \times 3 \]
-
Perform the division: \[ 0.8 \div 8 = 0.1 \] Now the expression is: \[ 0.1 + 4 \times 3 \]
-
Perform the multiplication: \[ 4 \times 3 = 12 \] Now the expression is: \[ 0.1 + 12 \]
-
Perform the addition: \[ 0.1 + 12 = 12.1 \]
So the simplified answer is \( 12.1 \).
