Answer 2

Let's break down the expression step by step:

1. Start with the first part: (3, 42 - 2 5/8) ÷ (1/50)

First, calculate the value inside the parentheses: 3, 42 - 2 5/8 = 3, 42 - (2 + 5/8) = 3, 42 - 2, 625

Now, perform the division: (3, 42 - 2, 625) ÷ (1/50)

To divide by a fraction, you can multiply by its reciprocal: (3, 42 - 2, 625) × (50/1)

Now, multiply the numbers: (3, 42 - 2, 625) × 50 = 1, 895 × 50 = 94, 750

So, the result of the first part is 94,750.

2. Moving on to the second part: 7.2 × 3.8 + (3.24 - 2.1312) ÷ 0.42

First, calculate the values inside the parentheses: 3.24 - 2.1312 = 1.1088

Now, calculate the multiplication and division: 7.2 × 3.8 + (1.1088 ÷ 0.42)

Perform the division: 1.1088 ÷ 0.42 ≈ 2.6390476 (rounded to several decimal places)

Now, continue with the addition and multiplication: 7.2 × 3.8 + 2.6390476 ≈ 27.36 + 2.6390476 ≈ 29.9990476

So, the result of the second part is approximately 29.9990476.

3. Finally, let's put it all together: 94,750 ÷ 29.9990476 ≈ 3158.3370673 (rounded to several decimal places)

So, the final result of the expression is approximately 3158.3370673.
