Answer 1

Ответ: 0

Пошаговое объяснение:

(6/35 - 4/7) + (1,8 + 4,3) - 5,7 = (6/35 - 20/35) + 6,1 - 5,7 = - 14/35 + 0,4 = - 2/5 + 2/5 = 0

Answer 2

Ответ:

(-2/5)-(-6,1)-5,7=0,4+6,1-5,7=0

Answer 3

To solve this expression, let's break it down step by step:

1. Simplify the fractions:

   • $\frac{6}{35} - \frac{4}{7} = \frac{6 \times 7}{35 \times 7} - \frac{4 \times 5}{7 \times 5} = \frac{42}{245} - \frac{20}{35} = \frac{42}{245} - \frac{4}{7}$

2. Find a common denominator for the fractions in the second term:

   • $1.8 + 4.3 = 6.1$

3. Now the expression becomes: $\frac{42}{245} - \frac{4}{7} + 6.1 - 5.7$

4. Continue simplifying:

   • $\frac{42}{245} - \frac{4 \times 35}{7 \times 35} = \frac{42}{245} - \frac{140}{245} = -\frac{98}{245}$
   • $6.1 - 5.7 = 0.4$

5. Combine the results: $-\frac{98}{245} + 0.4 = \frac{0.4 \times 245}{245} - \frac{98}{245} = \frac{98 - 98}{245} = 0$

So, the final result of the expression $\left( \frac{6}{35} - \frac{4}{7} \right) + (1.8 + 4.3) - 5.7$ is $0$.
