Answer 1

Ответ:

Правильный ответ 1,25

Answer 2

Let's break down the expression step by step:

1. First, simplify the fractions within each pair of parentheses:

   • $2 \frac{12}{17} = \frac{34}{17}$
   • $1 \frac{5}{17} = \frac{22}{17}$
   • $3 \frac{2}{5} = \frac{17}{5}$
   • $1 \frac{3}{5} = \frac{8}{5}$

2. Perform the addition and subtraction operations within each pair of parentheses:

   • $\frac{34}{17} + \frac{22}{17} = \frac{56}{17}$
   • $\frac{17}{5} + \frac{8}{5} = \frac{25}{5} = 5$

3. Divide the results of step 2 by 4:

   • $\frac{56}{17} \div 4 \approx 3.294$
   • $5 \div 4 = 1.25$

4. Subtract the results of step 3:

   • $3.294 - 1.25 \approx 2.044$

So, the result of the expression $10:(2 \frac{12}{17} + 1 \frac{5}{17}) - (3 \frac{2}{5} + 1 \frac{3}{5}):4$ is approximately $2.044$.
