Solution - Long multiplication
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths |
| 0 | . | 0 | 0 | 0 | 1 | 4 | 5 | |
| × | 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 6 decimal place(s). So once calculated, the result will be reduced by the factor of 1,000,000.
| Place value | thousands | hundreds | tens | ones |
| 1 | 4 | 5 | ||
| × | 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 145, from right to left.
Multiply the ones digit (8) of the multiplicator by the number in the ones place value:
8×5=40
Write 0 in the ones place.
Because the result is greater than 9, carry the 4 to the tens place.
| Place value | thousands | hundreds | tens | ones |
| 4 | ||||
| 1 | 4 | 5 | ||
| × | 8 | |||
| 0 |
Multiply the ones digit (8) of the multiplicator by the number in the tens place value and add the carried number (4):
8×4+4=36
Write 6 in the tens place.
Because the result is greater than 9, carry the 3 to the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 3 | 4 | |||
| 1 | 4 | 5 | ||
| × | 8 | |||
| 6 | 0 |
Multiply the ones digit (8) of the multiplicator by the number in the hundreds place value and add the carried number (3):
8×1+3=11
Write 1 in the hundreds place.
Because the result is greater than 9, carry the 1 to the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 1 | 3 | 4 | ||
| 1 | 4 | 5 | ||
| × | 8 | |||
| 1 | 1 | 6 | 0 |
Because we have 6 digit(s) to the right of the decimal point in the numbers that are being multiplied, we move the decimal point 6 time(s) to the left (reducing the result by the factor of 1,000,000) to get the final result:
The solution is: 0.00116
