Megoldás - Long multiplication
Lépésről lépésre magyarázat
1. Rewrite the numbers from top to bottom aligned to the right
| Helyiérték | egyesek | . | tizedek | századok | ezredek |
| 0 | , | 0 | 1 | 5 | |
| × | 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 4 decimal place(s). So once calculated, the result will be reduced by the factor of 10 000.
| Helyiérték | százasok | tízesek | egyesek |
| 1 | 5 | ||
| × | 8 | ||
2. Multiply the numbers using long multiplication method
Start by multiplying the egyesek digit (8) of the multiplier 8 by each digit of the multiplicand 15, from right to left.
Multiply the egyesek digit (8) of the multiplicator by the number in the egyesek place value:
8×5=40
Write 0 in the egyesek place.
Because the result is greater than 9, carry the 4 to the tízesek place.
| Helyiérték | százasok | tízesek | egyesek |
| 4 | |||
| 1 | 5 | ||
| × | 8 | ||
| 0 |
3. Add the partial products
Multiply the egyesek digit (8) of the multiplicator by the number in the tízesek place value and add the carried number (4):
8×1+4=12
Write 2 in the tízesek place.
Because the result is greater than 9, carry the 1 to the százasok place.
| Helyiérték | százasok | tízesek | egyesek |
| 1 | 4 | ||
| 1 | 5 | ||
| × | 8 | ||
| 1 | 2 | 0 |
Because we have 4 digit(s) to the right of the decimal point in the numbers that are being multiplied, we move the decimal point 4 time(s) to the left (reducing the result by the factor of 10 000) to get the final result:
The solution is: 0,012
