Answer 2

To simplify the given expression:

(3,4 ÷ 17 + 1,7 ÷ 34) × 4,2 + 8,25 ÷ 3

Let's break it down step by step:

1. Start with the divisions:

   • 3.4 ÷ 17 = 0.2
   • 1.7 ÷ 34 = 0.05

2. Replace the divisions in the expression:

   • (0.2 + 0.05) × 4.2 + 8.25 ÷ 3

3. Simplify further:

   • (0.25) × 4.2 + 8.25 ÷ 3

4. Now, multiply 0.25 by 4.2:

   • 1.05 + 8.25 ÷ 3

5. Finally, divide 8.25 by 3:

   • 1.05 + 2.75

6. Add the two results together:

   • 1.05 + 2.75 = 3.8

So, the simplified value of the expression is 3.8.
