Which one of the following choices does not equal any of the other choices?

Options

A. 5.43 + 4.63 - 3.24 - 2.32
B. 5.53 + 4.73 - 3.34 - 2.42
C. 5.53 + 4.53 - 3.34 - 2.22
D. 5.43 + 4.73 - 3.14 - 2.22

Answer

To solve the problem, we need to calculate the values of each option and determine which one does not equal the others.

### Step-by-Step Solution:

1. **Calculate Option A:**
\[ \text{Option A} = 5.43 + 4.63 - 3.24 - 2.32 \]
- First, add \(5.43\) and \(4.63\):
\[ 5.43 + 4.63 = 10.06 \]
- Next, subtract \(3.24\):
\[ 10.06 - 3.24 = 6.82 \]
- Finally, subtract \(2.32\):
\[ 6.82 - 2.32 = 4.50 \]
- Therefore, Option A equals \(4.50\).

2. **Calculate Option B:**
\[ \text{Option B} = 5.53 + 4.73 - 3.34 - 2.42 \]
- First, add \(5.53\) and \(4.73\):
\[ 5.53 + 4.73 = 10.26 \]
- Next, subtract \(3.34\):
\[ 10.26 - 3.34 = 6.92 \]
- Finally, subtract \(2.42\):
\[ 6.92 - 2.42 = 4.50 \]
- Therefore, Option B equals \(4.50\).

3. **Calculate Option C:**
\[ \text{Option C} = 5.53 + 4.53 - 3.34 - 2.22 \]
- First, add \(5.53\) and \(4.53\):
\[ 5.53 + 4.53 = 10.06 \]
- Next, subtract \(3.34\):
\[ 10.06 - 3.34 = 6.72 \]
- Finally, subtract \(2.22\):
\[ 6.72 - 2.22 = 4.50 \]
- Therefore, Option C equals \(4.50\).

4. **Calculate Option D:**
\[ \text{Option D} = 5.43 + 4.73 - 3.14 - 2.22 \]
- First, add \(5.43\) and \(4.73\):
\[ 5.43 + 4.73 = 10.16 \]
- Next, subtract \(3.14\):
\[ 10.16 - 3.14 = 7.02 \]
- Finally, subtract \(2.22\):
\[ 7.02 - 2.22 = 4.80 \]
- Therefore, Option D equals \(4.80\).

### Conclusion:
After calculating all options:
- Option A = \(4.50\)
- Option B = \(4.50\)
- Option C = \(4.50\)
- Option D = \(4.80\)

Thus, the option that does not equal any of the other choices is **Option D**.
