To simplify the expression (1.1−0.3)÷8+4×3, we need to follow the order of operations (PEMDAS/BODMAS).
-
First, calculate the parentheses: \( 1.1 - 0.3 = 0.8 \)
-
Now the expression looks like this: \( 0.8 ÷ 8 + 4 × 3 \)
-
Next, perform the division: \( 0.8 ÷ 8 = 0.1 \)
-
Now the expression is: \( 0.1 + 4 × 3 \)
-
Next, perform the multiplication: \( 4 × 3 = 12 \)
-
Now the expression is: \( 0.1 + 12 \)
-
Finally, perform the addition: \( 0.1 + 12 = 12.1 \)
The final answer is 12.1.
