Answer 3

To simplify the 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). Here's the step-by-step simplification of the expression:

1. Start with the innermost parentheses:

   • (-5 1/2 + 5/4 * 3 1/5)

2. Next, calculate the multiplication and addition within the parentheses:

   • (-5 1/2 + 15/4 1/5)

3. Convert the mixed numbers to improper fractions:

   • (-11/2 + 75/4 1/5)

4. Find a common denominator for the fractions:

   • (-55/10 + 375/40 8/40)

5. Add the fractions:

   • (-55/10 + 375/40 + 8/40)

6. Calculate the addition:

   • (-55/10 + 383/40)

7. Simplify further by finding a common denominator for the fractions:

   • (-220/40 + 383/40)

8. Add the fractions:

   • (163/40)

Now that you have simplified the expression inside the parentheses, you can proceed with the rest of the calculation:

9. Divide the result by 9/10:

   • (163/40) ÷ (9/10)

10. To divide by a fraction, you can multiply by its reciprocal (flip it):

• (163/40) * (10/9)

11. Multiply the fractions:

• (163 * 10) / (40 * 9)

12. Calculate the numerator and denominator separately:

• (1630) / (360)

13. Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (in this case, 10):

• (163) / (36)

So, the simplified result of the expression is 163/36.
