Пошаговое объяснение:

1.5 - 1/3 = 7/6

7/6 Х 2   6/7 = 3   1/3

Answer 3

To solve the expression (1 + 5 - 1/3) × 2 + 6/7, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's proceed step by step:

Step 1: Calculate inside the parentheses. 1 + 5 - 1/3 = 6 - 1/3

Step 2: Perform the subtraction. 6 - 1/3 = (18/3) - 1/3 = 17/3

Step 3: Multiply the result by 2. (17/3) × 2 = 17/3 × 2 = 34/3

Step 4: Add 6/7 to the result. 34/3 + 6/7

To add these fractions, they need a common denominator. The common denominator for 3 and 7 is 21.

Step 5: Convert fractions to a common denominator and perform the addition. (34/3) * (7/7) = (238/21) + (18/21) = (238 + 18) / 21 = 256/21

So, the result of the expression is 256/21.
