Answer 3

To calculate the expression (12-5,4) × 4,5 + 6,9 ÷ 1,5, you should follow the order of operations (PEMDAS/BODMAS - Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction):

1. Start with the subtraction inside the parentheses: 12 - 5.4 = 6.6

2. Next, multiply the result by 4.5: 6.6 × 4.5 = 29.7

3. Finally, divide the previous result by 1.5: 29.7 ÷ 1.5 = 19.8

So, the final answer is 19.8.
