__________
Step 2: Multiply the ones place digit of the bottom number (7) by the top number (13.6):
13.6
x 4.7
__________
76
Step 3: Multiply the tens place digit of the bottom number (4) by the top number (13.6):
13.6
x 4.7
__________
544
__________
Step 4: Add the two products together:
13.6

Therefore, 13.6 multiplied by 4.7 equals 63.92.
To multiply 13.6 and 4.7, you can follow these steps:
1. Write down the two numbers, 13.6 and 4.7, vertically.
```
13.6
x 4.7
```
2. Start by multiplying the ones place digits, which are 6 and 7, without considering the decimal point. Multiply these two numbers: 6 * 7 = 42.
3. Write down the result below the line and consider the decimal point. Since there are two decimal places in total (one in 13.6 and one in 4.7), the decimal point should be placed two places from the right.
```
13.6
x 4.7
-----------
42
```
4. Now, consider the tenths place digit of the bottom number, which is 4, and multiply it with the whole number on the top, which is 13: 4 * 13 = 52.
5. Write down the result below the line, shifted one place to the left because our multiplication is in the tenths place.
```
13.6
x 4.7
-----------
42
52
```
6. Next, consider the hundredths place digit of the bottom number, which is 0. Multiply this digit with the whole number on top, 13: 0 * 13 = 0.
7. Write a 0 below the line, but remember to shift it two places to the left since the multiplication is in the hundredths place.
```
13.6
x 4.7
-----------
42
52
0
```
8. Add up all the results we obtained:
```
13.6
x 4.7
-----------
42
52
0
-----------
63.92
```
Therefore, the product of 13.6 and 4.7 is 63.92.
