If 112 ones + 12 thousand = 11012 + ....... tens, then the number in the blank space is

Options

A. 111
B. 112
C. 101
D. 110

Answer

To solve the problem, we need to find the value that goes in the blank space in the equation:

\[ 112 \text{ ones} + 12,000 = 11,012 + \text{ (blank)} \text{ tens} \]

Let's break it down step by step:

### Step 1: Convert the ones and thousands to their numerical values
- **112 ones** can be written as:
\[ 112 \times 1 = 112 \]
- **12 thousand** can be written as:
\[ 12,000 \]

### Step 2: Combine the values
Now, we add the values we calculated:
\[ 112 + 12,000 = 12,112 \]

### Step 3: Set up the equation
We now have:
\[ 12,112 = 11,012 + \text{ (blank)} \text{ tens} \]
Let the number of tens in the blank space be \( x \). Therefore, we can express the tens as:
\[ 10x \]
Now, we rewrite the equation:
\[ 12,112 = 11,012 + 10x \]

### Step 4: Isolate \( 10x \)
To find \( 10x \), we subtract \( 11,012 \) from both sides:
\[ 12,112 - 11,012 = 10x \]
Calculating the left side:
\[ 1,100 = 10x \]

### Step 5: Solve for \( x \)
Now, we divide both sides by 10 to find \( x \):
\[ x = \frac{1,100}{10} = 110 \]

### Conclusion
The number in the blank space is:
\[ \boxed{110} \]
