Ответ: 0

Answer 2

To solve this problem, we need to find a common denominator for all four fractions. The least common multiple of 8 and 7 is 56. So we can rewrite the fractions with denominators of 56 as follows:

3/8 = 21/56 2/7 = 16/56 5/8 = 35/56 5/7 = 40/56

Now we can substitute these equivalent fractions into the original equation:

21/56 - 16/56 + 35/56 - 40/56

We can combine the like terms by adding and subtracting the numerators:

(21 + 35) / 56 - (16 + 40) / 56

56/56 - 56/56

0

Therefore, the solution is 0.
