Answer 2

To solve this expression, you can follow the order of operations (PEMDAS/BODMAS) to simplify it step by step.

PEMDAS/BODMAS 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 this case, there are no parentheses or exponents, so we'll start with multiplication and division:

1. First, simplify the fractions:

   • 5/17 + 12/17 = (5 + 12)/17 = 17/17 = 1

2. Now, your expression becomes:

   23:(6 1 + 4 2/5 - 2 3/5):5

3. Continue with the addition and subtraction:

   • 6 1 + 4 2/5 - 2 3/5 = 6 + 4 2/5 - 2 3/5

4. Now, subtract the mixed numbers:

   • 4 2/5 - 2 3/5 = (4 - 2) + (2/5 - 3/5) = 2 + (-1/5)

5. The expression now looks like this:

   23:(6 + 2 + (-1/5)):5

6. Perform the addition inside the parentheses:

   • 6 + 2 + (-1/5) = 8 - 1/5

7. The expression now looks like this:

   23:(8 - 1/5):5

8. Next, perform the subtraction inside the parentheses:

   • 8 - 1/5 = 40/5 - 1/5 = 39/5

9. Now, the expression is:

   23:(39/5):5

10. Finally, perform the division:

    • 23 ÷ (39/5) ÷ 5

To divide by a fraction, you can multiply by its reciprocal:

- 23 * (5/39) * 1/5

11. Now, perform the multiplication:

- (23 * 5/39) * 1/5 = (115/39) * 1/5

12. Multiply the fractions:

scssCopy code
- (115/39) * (1/5) = 115/195 = 23/39

So, the final answer is 23/39.
