Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Let's break it down step by step:

1. First, we'll deal with the numbers in parentheses:

   (2 + 1 2/5) = 2 + (7/5) = 2 + 1.4 = 3.4

2. Now, we have:

   10 - 3 3/4 * 3.4 * 1 5/9

3. Next, we'll multiply:

   3 3/4 * 3.4 = 15/4 * 3.4 = 51/10 * 34/10 = (51 * 34) / (10 * 10) = 1734 / 100 = 867/50

4. Now, we have:

   10 - (867/50) * 1 5/9

5. To multiply a whole number by a fraction, you can convert the whole number to a fraction with the same denominator:

   1 5/9 = 9/9 + 5/9 = 14/9

6. Now we have:

   10 - (867/50) * (14/9)

7. Multiply the fractions:

   (867/50) * (14/9) = (867 * 14) / (50 * 9) = 12138 / 450

8. Now, we have:

   10 - (12138/450)

9. To subtract fractions, they need the same denominator:

   10 = 450/45 (multiply numerator and denominator by 45)

10. Subtract the fractions:

    (450/45) - (12138/450) = (450/45) - (12138/450)

11. Find a common denominator, which is 450:

    (450/45) - (12138/450) = (450/45) - (12138/450) * (10/10)

12. Subtract:

    (450/45) - (121380/4500) = (4500/450) - (121380/4500)

13. Now subtract the fractions:

    (4500/450) - (121380/4500) = (4500 - 121380) / 4500

14. Simplify the numerator:

    (4500 - 121380) = -116880

15. So, the final result is:

    -116880 / 4500

Now, we can simplify this fraction further. Both the numerator and denominator have a common factor of 60:

-116880 / 4500 = (-1948/75)

So, the final result is -1948/75.
