Answer 2

Ответ:

1 13/15

Пошаговое объяснение:
12 2/15-(7 11/15 + 2 8/15)
182/15-((7+2)+(11/15+8/15))
182/15-(9+19/15)
182/15-(9+1 4/15)
182/15-(9+1+4/15)
182/15-(10+4/15)
182/15-10 4/15 = 182/15-154/15 = 28/15 = 1 13/15

Answer 3

To solve the expression 12 + 2/15 - (7 + 11/15 + 2 + 8/15), we can follow the order of operations (PEMDAS/BODMAS) to simplify the expression step by step.

Step 1: Addition and Subtraction within Parentheses

Inside the parentheses, we have 7 + 11/15 + 2 + 8/15. We can add the whole numbers and fractions separately.

- 7 + 2 = 9 - 11/15 + 8/15 = 19/15

So, the expression inside the parentheses simplifies to 9 + 19/15.

Step 2: Addition and Subtraction

Now, we can substitute the simplified expression back into the original expression:

12 + 2/15 - (9 + 19/15)

- 12 + 2/15 - 9 = 3 + 2/15 - 3 + 2/15 - 19/15 = (3 - 19)/15 = -16/15

Therefore, the value of the expression 12 + 2/15 - (7 + 11/15 + 2 + 8/15) is -16/15.

Please note that the above solution is based on the order of operations and the given expression.
