Answer 3

To solve this expression, we'll 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). In your expression, there are no parentheses or exponents, so we'll perform multiplication and division first, followed by addition and subtraction:

1. Start with the multiplication and division:

   • 1/8 + 2/9 - (1/4 × 5 1/7) ÷ (7/9 - 2/3 + 1/6)

2. Calculate the products and divisions inside the parentheses:

   • 1/8 + 2/9 - (5/4 × 1/7) ÷ (7/9 - 2/3 + 1/6)

3. Calculate the products and divisions:

   • 1/8 + 2/9 - (5/28) ÷ (7/9 - 2/3 + 1/6)

4. Now, let's simplify the expression inside the parentheses:

   • 1/8 + 2/9 - (5/28) ÷ (21/9 - 14/9 + 3/9)

5. Continue to simplify inside the parentheses:

   • 1/8 + 2/9 - (5/28) ÷ (10/9)

6. Calculate the division inside the parentheses:

   • 1/8 + 2/9 - (5/28) × (9/10)

7. Calculate the products inside the parentheses:

   • 1/8 + 2/9 - (45/280)

8. Simplify the fractions:

   • 1/8 + 2/9 - 45/280

9. Find a common denominator for the fractions:

   • (35/280) + (64/280) - (45/280)

10. Add and subtract the fractions:

• (35/280 + 64/280) - 45/280

11. Combine the fractions:

• (99/280) - 45/280

12. Subtract the fractions:

• (99/280 - 45/280)

13. Simplify the result:

• 54/280

14. Reduce the fraction to its simplest form:

• 27/140

So, the simplified value of the expression is 27/140.
