Answer 2

To solve the expression 40.27 × (6.38 + 7.62) - (47.45 + 9.25) ÷ 21, you need to follow the order of operations, also known as PEMDAS/BODMAS (Parentheses, Exponents, Multiplication/Division, and Addition/Subtraction). Let's break down the calculation step by step:

Step 1: Calculate the addition inside the parentheses: 6.38 + 7.62 = 14

Step 2: Calculate the addition and division outside the parentheses: 47.45 + 9.25 = 56.7 56.7 ÷ 21 ≈ 2.7

Step 3: Calculate the multiplication and subtraction: 40.27 × 14 - 2.7 = 563.78 - 2.7 ≈ 561.08

Therefore, the result of the expression 40.27 × (6.38 + 7.62) - (47.45 + 9.25) ÷ 21 is approximately 561.08.
