Answer 3

To solve the given expression, follow these steps:

Step 1: Convert mixed numbers to improper fractions (if applicable). Step 2: Perform the operations inside the parentheses first. Step 3: Perform the division and subtraction from left to right.

Given expression:

1. Convert mixed numbers to improper fractions: 3 3/8 = (8 * 3 + 3) / 8 = 27 / 8 9,54 = 9 + 0.54 = 9 + 54/100 = 9 + 27/50

2. Perform the operations inside the parentheses first: (27/8 • 4/9) + (9 + 27/50) ÷ (5.1 - 2.8)

3. Perform the multiplication and division from left to right: (27/8 • 4/9) = (27 * 4) / (8 * 9) = 108 / 72 = 3/2

   (9 + 27/50) ÷ (5.1 - 2.8) = (9 + 27/50) ÷ 2.3 = (450/50 + 27/50) ÷ 2.3 = (477/50) ÷ 2.3 = (477/50) * (1/2.3) = 477 / (50 * 2.3) ≈ 477 / 115

4. Perform the addition and subtraction from left to right: 3/2 + 477/115

   To add these fractions, we need to find a common denominator. The least common multiple (LCM) of 2 and 115 is 230. Convert both fractions to have a denominator of 230:

   (3/2) * (115/115) = 345/230 (477/115) * (2/2) = 954/230

   Now, add the fractions: 345/230 + 954/230 = (345 + 954) / 230 = 1299 / 230

Now, the final result is: 3/2 + 477/115 = 1299/230
