Answer 2

To solve this expression, follow the order of operations: PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

1. Perform division first: 72/73 * 34/65 + 72/73 * 39/65

2. Then perform the multiplications: (72 * 34) / (73 * 65) + (72 * 39) / (73 * 65)

3. Calculate the numerator of each fraction: (2448) / (4745) + (2808) / (4745)

4. Find the common denominator and add the fractions: (2448 + 2808) / 4745

5. Finally, add the numerators: 5256 / 4745

Now, if you want to get the decimal approximation of this fraction, simply divide the numerator by the denominator:

5256 ÷ 4745 ≈ 1.1076 (rounded to four decimal places)
