4+1
______
4 1/4
one over 4 plus (1 over 4 + 1 over 4 1/4)) the numerator in the denominator is 1.

To simplify the given expression, let's break down each step:

1. Start with the expression: 4 + 1 ÷ (4 + 1 ÷ 4 + 1 ÷ 4 1/4)

2. The first step is to evaluate the denominator inside the parentheses: 4 + 1 ÷ (4 + 1 ÷ 4 + 1 ÷ (4 + 1/4))

3. Next, simplify the numerator inside the parentheses: 4 + 1 ÷ (4 + 1 ÷ 4 + 1 ÷ (4 + 1/4))

The numerator is already a simplified expression, so we can move on to the next step.

4. Evaluate the innermost parentheses: 4 + 1 ÷ (4 + 1 ÷ 4 + 1 ÷ (4 + 1/4))

In this case, the innermost parentheses contain an addition operation (4 + 1/4), which gives us the sum of 4 1/4.

5. Replace the simplified expression in the parentheses: 4 + 1 ÷ (4 + 1 ÷ 4 + 1 ÷ 4 1/4)

So, our expression becomes: 4 + 1 ÷ (4 + 1 ÷ 4 + 1 ÷ 4 1/4)

6. Evaluate the denominator: 4 + 1 ÷ (4 + 1 ÷ 4 + 1 ÷ 4 1/4)

The denominator contains the sum of 4 and 1/4, which is equal to 4 1/4.

7. Replace the simplified expression for the denominator: 4 + 1 ÷ (4 + 1 ÷ 4 + 1 ÷ 4 1/4)

The expression now becomes: 4 + 1 ÷ (4 + 1 ÷ 4 + 1 ÷ 4 1/4)

8. Evaluate the remaining addition operation before the division: 4 + 1 ÷ (4 + 1 ÷ 4 + 1 ÷ 4 1/4)

The addition operation: 4 + 1 ÷ 4 gives us the sum of 4 1/4.

9. Replace the simplified expression for the addition: 4 + 1 ÷ (4 + 1 ÷ 4 + 1 ÷ 4 1/4)

The expression now becomes: 4 + 1 ÷ (4 1/4 + 1 ÷ 4 1/4)

10. Finally, evaluate the division operation: 1 ÷ (4 1/4 + 1 ÷ 4 1/4)

The division operation: 1 ÷ 4 1/4 is equal to 1/4.

11. Replace the simplified expression for the division: 4 + 1 ÷ (4 1/4 + 1 ÷ 4 1/4)

The expression now becomes: 4 + 1 ÷ (4 1/4 + 1/4)

12. Continue to simplify the expression: 4 + 1 ÷ (4 1/4 + 1/4)

In this case, the addition operation: 4 1/4 + 1/4 is equal to 4 3/4.

13. Replace the simplified expression for the addition: 4 + 1 ÷ (4 3/4)

The expression now becomes: 4 + 1 ÷ 4 3/4

14. Evaluate the division operation: 1 ÷ 4 3/4

To divide by a mixed number, we multiply the numerator by the reciprocal of the denominator. In this case, the reciprocal of 4 3/4 is 4/19.

So, the division becomes: 1 × 4/19 = 4/19

15. Replace the simplified expression for the division: 4 + 4/19

The expression now becomes: 4 + 4/19

16. Finally, combine the terms: 4 + 4/19

To add mixed numbers, we find a common denominator. In this case, we can find the common denominator as 19.

17. Multiply the whole number (4) by the denominator (19) and add the numerator (4) for a new numerator of 76.

The expression becomes: 76/19 + 4/19

18. Add the numerators: 76/19 + 4/19 = 80/19

So, the simplified expression is 80/19.
