Options

A. 103.722
B. 1.03722
C. 10.3722
D. None of these

Answer

To find the sum of the numbers 2.363, 7.965, 0.0363, and 0.0079, we will follow these steps:

### Step 1: Align the Numbers
First, we need to align the numbers by their decimal points for easier addition. We can write them as follows:

```
2.3630
7.9650
0.0363
0.0079
```

### Step 2: Add Zeros
Since the maximum number of decimal places in our numbers is 4, we can add zeros to the end of the numbers that have fewer than 4 decimal places. This gives us:

```
2.3630
7.9650
0.0363
0.0079
```

### Step 3: Add the Numbers
Now, we will add the numbers column by column, starting from the rightmost column (the thousandths place):

1. **Thousandths place**: 0 + 0 + 3 + 9 = 12 (write down 2, carry over 1)
2. **Hundredths place**: 3 + 5 + 6 + 7 = 21 + 1 (carry) = 22 (write down 2, carry over 2)
3. **Tenths place**: 6 + 6 + 0 + 0 = 12 + 2 (carry) = 14 (write down 4, carry over 1)
4. **Units place**: 2 + 7 + 0 + 0 = 9 + 1 (carry) = 10 (write down 0, carry over 1)

Now we combine all the results:

```
10.3722
```

### Final Result
The sum of the numbers 2.363, 7.965, 0.0363, and 0.0079 is **10.3722**.
