Multiply the
`2.4 xx 3.1 xx1.5`

Answer

To solve the multiplication of \(2.4 \times 3.1 \times 1.5\), we can follow these steps:

### Step 1: Remove the decimals and multiply the numbers as whole numbers.
We will first multiply \(24\) (which is \(2.4\) multiplied by \(10\)) by \(15\) (which is \(1.5\) multiplied by \(10\)).

\[ 24 \times 15 \]

### Step 2: Perform the multiplication.
To multiply \(24\) by \(15\):
- Multiply \(24\) by \(5\):
\[ 24 \times 5 = 120 \]
- Multiply \(24\) by \(10\):
\[ 24 \times 10 = 240 \]
- Now add these two results:
\[ 120 + 240 = 360 \]

### Step 3: Determine the position of the decimal point.
In the original numbers, \(2.4\) has 1 decimal place, \(3.1\) has 1 decimal place, and \(1.5\) has 1 decimal place. This gives us a total of \(3\) decimal places.

So, we place the decimal point in \(360\) to get \(3.60\) (or simply \(3.6\)).

### Step 4: Now multiply the result \(3.6\) by \(3.1\).
Again, we will ignore the decimal and multiply \(36\) by \(31\).

\[ 36 \times 31 \]

### Step 5: Perform the multiplication.
To multiply \(36\) by \(31\):
- Multiply \(36\) by \(1\):
\[ 36 \times 1 = 36 \]
- Multiply \(36\) by \(30\):
\[ 36 \times 30 = 1080 \]
- Now add these two results:
\[ 36 + 1080 = 1116 \]

### Step 6: Determine the position of the decimal point again.
In \(3.6\) there is 1 decimal place and in \(3.1\) there is also 1 decimal place, giving us a total of \(2\) decimal places.

So, we place the decimal point in \(1116\) to get \(11.16\).

### Final Answer:
\[ 2.4 \times 3.1 \times 1.5 = 11.16 \]
