Пошаговое объяснение:

$- 2 \frac{5}{7} - 1 \frac{3}{14} = - 3 \frac{10 + 3}{14} = - 3 \frac{13}{14}$

Answer 2

To solve the expression -2 + 5/7 - 1 + 3/14, 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, we perform the division: 5/7 and 3/14. - 5 divided by 7 is approximately 0.7143. - 3 divided by 14 is approximately 0.2143.

2. Now, we substitute the division results back into the expression: -2 + 0.7143 - 1 + 0.2143.

3. Next, we perform the addition and subtraction operations from left to right: - -2 + 0.7143 = -1.2857 - -1.2857 - 1 = -2.2857 - -2.2857 + 0.2143 = -2.0714

Therefore, the value of the expression -2 + 5/7 - 1 + 3/14 is approximately -2.0714.

Please note that the values provided are approximate due to rounding.
