Answer 2

To evaluate the expression (8 - 1.6) × 4.5 + 0.9728 ÷ 3.2, we need to follow the order of operations, also known as the PEMDAS/BODMAS rule (Parentheses/Brackets, Orders/Exponents, Division/Multiplication, Addition/Subtraction):

Step 1: Perform the subtraction within the parentheses: 8 - 1.6 = 6.4

Step 2: Perform the multiplication: 6.4 × 4.5 = 28.8

Step 3: Perform the division: 0.9728 ÷ 3.2 ≈ 0.304

Step 4: Perform the addition: 28.8 + 0.304 ≈ 29.104

Therefore, the value of the expression (8 - 1.6) × 4.5 + 0.9728 ÷ 3.2 is approximately 29.104.
