Answer 1

-5,05 вот так вышло )))

Answer 2

Let's break down the expression step by step:

1. First, let's simplify the fractions within the expression:

   • $4 \frac{3}{7}$ can be converted to an improper fraction: $\frac{31}{7}$
   • $3 \frac{1}{7}$ can be converted to an improper fraction: $\frac{22}{7}$
   • $1 \frac{1}{2}$ can be converted to an improper fraction: $\frac{3}{2}$

2. Next, let's subtract the fractions within the expression:

   • $\frac{31}{7} - \frac{22}{7} = \frac{31 - 22}{7} = \frac{9}{7}$

3. Now, we can substitute the simplified fractions back into the expression: $8/9 - \frac{9}{7} = \frac{8}{9} - \frac{9}{7}$

To subtract these fractions, we need to find a common denominator. The least common multiple of 9 and 7 is 63.

4. Convert the fractions to have a common denominator of 63: $\frac{8}{9} = \frac{8 \times 7}{9 \times 7} = \frac{56}{63}$ $\frac{9}{7} = \frac{9 \times 9}{7 \times 9} = \frac{81}{63}$

5. Subtract the fractions: $\frac{56}{63} - \frac{81}{63} = \frac{56 - 81}{63} = \frac{-25}{63}$

So, the final result of the expression is $-\frac{25}{63}$.
