Answer 1

1,12•(-2/7)+13:5-6 2/5=28/25•(-2/7)+2,6-32/5=-4/25•2+13/5-32/5=-8/25+13/5-32/5=-103/25=-4 3/25 або -4,12

Answer 2

Let's break down the expression step by step:

1. Start with the multiplication and division inside parentheses:

   $1 \times \left(-\frac{2}{7}\right) + \frac{13}{5} - \frac{6}{5}$

   $= -\frac{2}{7} + \frac{13}{5} - \frac{6}{5}$

2. Find a common denominator for the fractions with different denominators, which is 35 in this case:

   $= -\frac{10}{35} + \frac{91}{35} - \frac{42}{35}$

3. Combine the fractions:

   $= \frac{-10 + 91 - 42}{35}$

   $= \frac{39}{35}$

4. Now simplify the fraction:

   $= 1 \frac{4}{35}$

So, $1 - \frac{31}{35}$ simplifies to $1 \frac{4}{35}$.
