Solution - Long multiplication
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | tens | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths |
| 6 | 8 | |||||||
| × | 0 | . | 0 | 0 | 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 5 decimal place(s). So once calculated, the result will be reduced by the factor of 100,000.
| Place value | hundreds | tens | ones |
| 6 | 8 | ||
| × | 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 68, from right to left.
Multiply the ones digit (8) of the multiplicator by the number in the ones place value:
8×8=64
Write 4 in the ones place.
Because the result is greater than 9, carry the 6 to the tens place.
| Place value | hundreds | tens | ones |
| 6 | |||
| 6 | 8 | ||
| × | 8 | ||
| 4 |
3. Add the partial products
Multiply the ones digit (8) of the multiplicator by the number in the tens place value and add the carried number (6):
8×6+6=54
Write 4 in the tens place.
Because the result is greater than 9, carry the 5 to the hundreds place.
| Place value | hundreds | tens | ones |
| 5 | 6 | ||
| 6 | 8 | ||
| × | 8 | ||
| 5 | 4 | 4 |
Because we have 5 digit(s) to the right of the decimal point in the numbers that are being multiplied, we move the decimal point 5 time(s) to the left (reducing the result by the factor of 100,000) to get the final result:
The solution is: 0.00544
