Answer 1

19-(3 целые5/7+6целых3/7)

Answer 2

To solve the expression, let's simplify each part step by step:

First, let's simplify the fraction inside the parentheses:

3 and 5/7 can be written as an improper fraction: (3 * 7 + 5) / 7 = 22/7

6 and 3/7 can be written as an improper fraction: (6 * 7 + 3) / 7 = 45/7

Now, let's substitute these values back into the expression:

19 - (22/7 + 45/7)

To add these fractions, they need to have a common denominator. In this case, the common denominator is 7.

19 - (22/7 + 45/7) = 19 - (22 + 45) / 7 = 19 - 67/7

To subtract fractions, they also need a common denominator. The common denominator here is still 7.

19 - 67/7 = (19 * 7) / 7 - 67/7 = 133/7 - 67/7 = (133 - 67) / 7 = 66/7

Therefore, the simplified expression is 66/7.
