Megoldás - Long multiplication
Lépésről lépésre magyarázat
1. Rewrite the numbers from top to bottom aligned to the right
| Helyiérték | egyesek | . | tizedek | századok | ezredek | tízezredek |
| 0 | , | 0 | 0 | 2 | 8 | |
| × | 0 | , | 0 | 0 | 0 | 1 |
| , |
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 8 decimal place(s). So once calculated, the result will be reduced by the factor of 100 000 000.
| Helyiérték | tízesek | egyesek |
| 2 | 8 | |
| × | 1 | |
2. Multiply the numbers using long multiplication method
Start by multiplying the egyesek digit (1) of the multiplier 1 by each digit of the multiplicand 28, from right to left.
Multiply the egyesek digit (1) of the multiplicator by the number in the egyesek place value:
1×8=8
Write 8 in the egyesek place.
| Helyiérték | tízesek | egyesek |
| 2 | 8 | |
| × | 1 | |
| 8 |
3. Add the partial products
Multiply the egyesek digit (1) of the multiplicator by the number in the tízesek place value:
1×2=2
Write 2 in the tízesek place.
| Helyiérték | tízesek | egyesek |
| 2 | 8 | |
| × | 1 | |
| 2 | 8 |
Because we have 8 digit(s) to the right of the decimal point in the numbers that are being multiplied, we move the decimal point 8 time(s) to the left (reducing the result by the factor of 100 000 000) to get the final result:
The solution is: 0,00000028
