Question

(1,3-4)×1/2 +(-4/5-2/7) ÷1/8​

Answer 1

Ответ:

-281/28

Пошаговое объяснение:

1)-2,7*1/2-38/35*8

2)-27/10/1/2-304/35

3)-27/20-304/35

Answer 2

Let's break down the expression and solve it step by step using the order of operations (PEMDAS):

1. First, we need to simplify the expression inside the parentheses: (1,3-4) = (1,-1)

2. Next, we can distribute the multiplication by 1/2: (1,-1) × 1/2 = (1/2,-1/2)

3. Now, let's simplify the expression inside the second set of parentheses: (-4/5-2/7) = (-28/35 - 10/35) = -38/35

4. Finally, we need to divide -38/35 by 1/8: (-38/35) ÷ (1/8) = (-38/35) × (8/1) = -304/35

5. Putting it all together, we have: (1,3-4)×1/2 +(-4/5-2/7) ÷1/8 = (1/2,-1/2) + (-304/35) = (-17/70, -1/2)

Therefore, the final answer is (-17/70, -1/2).
