Answer 1

Ответ:

11 7/15 -(4- 1 5/9)÷ 7/15 + 3/9 = 8 7/10

Answer 2

To solve the expression 11 + 7/15 - (4 - 1 + 5/9) ÷ 7/15 + 3/9, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Step 1: Simplify within parentheses

Inside the parentheses, we have the expression (4 - 1 + 5/9). Let's simplify it: 4 - 1 + 5/9 = 3 + 5/9

Step 2: Simplify multiplication and division

Now, let's simplify the division part of the expression: (3 + 5/9) ÷ 7/15 = (3 + 5/9) * (15/7)

Step 3: Simplify addition and subtraction

Finally, let's simplify the addition and subtraction part of the expression: 11 + 7/15 - (3 + 5/9) * (15/7) + 3/9

To perform the calculations, we need to find a common denominator for the fractions involved. The common denominator for 15, 9, and 7 is 315.

Step 4: Perform the calculations

11 + 7/15 - (3 + 5/9) * (15/7) + 3/9 = 11 + 7/15 - (3 * 45/63 + 5 * 35/63) + 3/9 = 11 + 7/15 - (135/63 + 175/63) + 3/9 = 11 + 7/15 - 310/63 + 3/9 = 11 + 7/15 - 310/63 + 21/63 = 11 + 7/15 - 289/63 = 11 + 7/15 - 289/63 * 15/15 = 11 + 7/15 - 4345/945 = 11 * 945/945 + 7/15 - 4345/945 = (11 * 945 + 7 * 63 - 4345) / 945 = (10395 + 441 - 4345) / 945 = 10395 + 441 - 4345 / 945 = 10395 + 441 - 4.6

Therefore, the result of the expression 11 + 7/15 - (4 - 1 + 5/9) ÷ 7/15 + 3/9 is approximately 10,051.4.

Please note that the result is rounded to one decimal place for simplicity.
