Ответ:

$(\frac{6}{5} -\frac{3}{7})*\frac{4}{8}=\frac{27}{70}$

Пошаговое объяснение:

1) $\frac{6}{5} - \frac{3}{7} =\frac{27}{35}$

2) $\frac{27}{35} *\frac{4}{8} =\frac{27}{70}$

Answer 3

To solve the expression (6/5 - 3/7) * 4/8, we can 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. Simplify the division inside the parentheses: - 6/5 = 1.2 - 3/7 = 0.42857142857142855

So, the expression becomes (1.2 - 0.42857142857142855) * 4/8.

2. Subtract the two values inside the parentheses: - 1.2 - 0.42857142857142855 = 0.7714285714285714

Now, the expression becomes 0.7714285714285714 * 4/8.

3. Simplify the division: - 4/8 = 0.5

The expression simplifies to 0.7714285714285714 * 0.5.

4. Multiply the two values: - 0.7714285714285714 * 0.5 = 0.38571428571428573

Therefore, the value of the expression (6/5 - 3/7) * 4/8 is approximately 0.3857.
