Answer 1

Аот правильный ответ))))))

Answer 2

To solve the expression (7 + 1/4 - 6 + 7/18) * 7.2 * 2.8, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

1. First, let's simplify the addition and subtraction inside the parentheses: 7 + 1/4 - 6 + 7/18 = 7.25 - 6 + 7/18

2. Next, let's simplify the addition and subtraction from left to right: 7.25 - 6 + 7/18 = 1.25 + 7/18

3. Now, let's find a common denominator for 7/18 and 1.25, which is 18: 1.25 = 1.25 * 18/18 = 22.5/18

4. Adding 7/18 and 22.5/18: 7/18 + 22.5/18 = (7 + 22.5)/18 = 29.5/18

5. Now, let's multiply the result by 7.2: (29.5/18) * 7.2 = (29.5 * 7.2) / 18

6. Finally, let's multiply the result by 2.8: ((29.5 * 7.2) / 18) * 2.8

To calculate the final result, we can use a calculator or perform the multiplication and division manually.

Please note that the expression you provided contains commas as decimal separators. In some regions, a comma is used as a decimal separator, while in others, a period is used. If you are in a region where a comma is used as a decimal separator, please replace the commas with periods before performing the calculations.
