Options

A. `15.04`
B. `9.1`
C. `9.64`
D. `15.14`

Answer

To solve the problem, we need to find "6 tenths more than the sum of 3.25 and 5.79." Let's break it down step by step.

### Step 1: Find the sum of 3.25 and 5.79
First, we need to add the two numbers together.

\[ 3.25 + 5.79 \]

Aligning the numbers for addition:

```
3.25
+ 5.79
-------
```

Now, we add the numbers column by column:

- In the hundredths place: \(5 + 9 = 14\) (write down 4 and carry over 1)
- In the tenths place: \(2 + 7 + 1 = 10\) (write down 0 and carry over 1)
- In the units place: \(3 + 5 + 1 = 9\)

So, the sum is:

\[ 3.25 + 5.79 = 9.04 \]

### Step 2: Convert 6 tenths to decimal
Next, we need to convert "6 tenths" into decimal form.

\[ 6 \text{ tenths} = \frac{6}{10} = 0.6 \]

### Step 3: Add 6 tenths to the sum
Now, we add 0.6 to the sum we calculated in Step 1.

\[ 9.04 + 0.6 \]

Aligning the numbers for addition:

```
9.04
+ 0.60
-------
```

Now, we add the numbers:

- In the hundredths place: \(4 + 0 = 4\)
- In the tenths place: \(0 + 6 = 6\)
- In the units place: \(9 + 0 = 9\)

So, the final result is:

\[ 9.04 + 0.6 = 9.64 \]

### Final Answer
Thus, 6 tenths more than the sum of 3.25 and 5.79 is:

\[ \boxed{9.64} \]
