Solution - Long multiplication
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 4 | 7 | 5 | . | 2 | ||
| × | 0 | . | 0 | 8 | ||
| . |
Ignore the decimal points and multiply as if these are whole numbers (as if each most right digit is the ones digit):
In this case we removed 3 decimal place(s). So once calculated, the result will be reduced by the factor of 1,000.
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 4 | 7 | 5 | 2 | ||
| × | 8 | ||||
2. Multiply the numbers using long multiplication method
Start by multiplying the ones digit (8) of the multiplier 8 by each digit of the multiplicand 4,752, from right to left.
Multiply the ones digit (8) of the multiplicator by the number in the ones place value:
8×2=16
Write 6 in the ones place.
Because the result is greater than 9, carry the 1 to the tens place.
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 1 | |||||
| 4 | 7 | 5 | 2 | ||
| × | 8 | ||||
| 6 |
Multiply the ones digit (8) of the multiplicator by the number in the tens place value and add the carried number (1):
8×5+1=41
Write 1 in the tens place.
Because the result is greater than 9, carry the 4 to the hundreds place.
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 4 | 1 | ||||
| 4 | 7 | 5 | 2 | ||
| × | 8 | ||||
| 1 | 6 |
Multiply the ones digit (8) of the multiplicator by the number in the hundreds place value and add the carried number (4):
8×7+4=60
Write 0 in the hundreds place.
Because the result is greater than 9, carry the 6 to the thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 6 | 4 | 1 | |||
| 4 | 7 | 5 | 2 | ||
| × | 8 | ||||
| 0 | 1 | 6 |
3. Add the partial products
Multiply the ones digit (8) of the multiplicator by the number in the thousands place value and add the carried number (6):
8×4+6=38
Write 8 in the thousands place.
Because the result is greater than 9, carry the 3 to the ten thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones |
| 3 | 6 | 4 | 1 | ||
| 4 | 7 | 5 | 2 | ||
| × | 8 | ||||
| 3 | 8 | 0 | 1 | 6 |
Because we have 3 digit(s) to the right of the decimal point in the numbers that are being multiplied, we move the decimal point 3 time(s) to the left (reducing the result by the factor of 1,000) to get the final result:
The solution is: 38.016
