By how much should `59.654` be decreased to get `48.5678` ?

Answer

To solve the problem of how much `59.654` should be decreased to get `48.5678`, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Problem**: We need to find out how much we should subtract from `59.654` to arrive at `48.5678`. This means we are looking for a number `x` such that when we subtract it from `59.654`, we get `48.5678`.

2. **Set Up the Equation**: We can express this mathematically as:
\[ 59.654 - x = 48.5678 \]

3. **Rearrange the Equation**: To find `x`, we need to isolate it on one side of the equation. We can do this by moving `x` to the right side and `48.5678` to the left side:
\[ x = 59.654 - 48.5678 \]

4. **Perform the Subtraction**: Now we will subtract `48.5678` from `59.654`. We can align the numbers for easier subtraction:
\[ \begin{array}{r} 59.6540 \\ - 48.5678 \\ \hline \end{array} \]

Starting from the rightmost digit:
- 0 - 8: We need to borrow, so it becomes 10 - 8 = 2 (and we borrow 1 from the 4, making it 3).
- 3 - 7: We need to borrow again, so it becomes 13 - 7 = 6 (and we borrow 1 from the 6, making it 5).
- 5 - 6: We need to borrow again, so it becomes 15 - 6 = 9 (and we borrow 1 from the 9, making it 8).
- 9 - 5 = 4.
- 5 - 4 = 1.

So, putting it all together:
\[ 59.654 - 48.5678 = 11.0862 \]

5. **Final Answer**: Therefore, `59.654` should be decreased by `11.0862` to get `48.5678`.

### Conclusion:
Thus, the answer is:
\[ \text{59.654 should be decreased by } 11.0862 \text{ to get } 48.5678. \]
