Simplify the given expression `:`
`5+ 0.6+ 0.03 + 0.004 + ( 9 xx 100) + ( 2 xx 10)`

Options

A. 529.364
B. 259.634
C. 925.634
D. 925.436

Answer

To simplify the expression \( 5 + 0.6 + 0.03 + 0.004 + (9 \times 100) + (2 \times 10) \), we can follow these steps:

### Step 1: Calculate the products
First, we need to calculate the products in the expression:
- \( 9 \times 100 = 900 \)
- \( 2 \times 10 = 20 \)

### Step 2: Rewrite the expression
Now, we can rewrite the expression by substituting the calculated values:
\[ 5 + 0.6 + 0.03 + 0.004 + 900 + 20 \]

### Step 3: Combine whole numbers
Next, we will combine the whole numbers (5, 900, and 20):
\[ 900 + 20 + 5 = 925 \]

### Step 4: Combine decimal numbers
Now, we will add the decimal numbers together:
\[ 0.6 + 0.03 + 0.004 \]

To do this, we can align the decimal points:
```
0.600
+ 0.030
+ 0.004
--------
```
Adding these together:
- \( 0.600 + 0.030 = 0.630 \)
- \( 0.630 + 0.004 = 0.634 \)

### Step 5: Combine the results
Now we can combine the whole number result with the decimal result:
\[ 925 + 0.634 = 925.634 \]

### Final Answer
The simplified expression is:
\[ \boxed{925.634} \]
