What is to be added to 63.58 to get 92?

Answer

To solve the question "What is to be added to 63.58 to get 92?", we can follow these steps:

### Step 1: Set up the equation
Let \( x \) be the number that we need to find. According to the question, we can write the equation as:
\[ x + 63.58 = 92 \]

### Step 2: Isolate \( x \)
To find \( x \), we need to isolate it on one side of the equation. We can do this by subtracting 63.58 from both sides:
\[ x = 92 - 63.58 \]

### Step 3: Perform the subtraction
Now, we will perform the subtraction:
1. Align the numbers by their decimal points:
```
92.00
- 63.58
```

2. Subtract starting from the rightmost digit:
- In the hundredths place: \( 0 - 8 \) (we need to borrow, so it becomes \( 10 - 8 = 2 \))
- In the tenths place: \( 0 - 5 \) (after borrowing, it becomes \( 9 - 5 = 4 \))
- In the units place: \( 2 - 3 \) (we need to borrow again, so it becomes \( 12 - 3 = 9 \))
- In the tens place: \( 9 - 6 = 3 \)

So, we have:
\[ 92 - 63.58 = 28.42 \]

### Step 4: Conclusion
Thus, the number that needs to be added to 63.58 to get 92 is:
\[ x = 28.42 \]

### Summary
To conclude, the answer is:
**28.42**
