Megoldás - Long multiplication
Lépésről lépésre magyarázat
1. Rewrite the numbers from top to bottom aligned to the right
| Helyiérték | egyesek | . | tizedek |
| 9 | |||
| × | 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 1 decimal place(s). So once calculated, the result will be reduced by the factor of 10.
| Helyiérték | tízesek | egyesek |
| 9 | ||
| × | 8 | |
2. Add the partial products
Start by multiplying the egyesek digit (8) of the multiplier 8 by each digit of the multiplicand 9, from right to left.
Multiply the egyesek digit (8) of the multiplicator by the number in the egyesek place value:
8×9=72
Write 2 in the egyesek place.
Because the result is greater than 9, carry the 7 to the tízesek place.
| Helyiérték | tízesek | egyesek |
| 7 | ||
| 9 | ||
| × | 8 | |
| 7 | 2 |
Because we have 1 digit(s) to the right of the decimal point in the numbers that are being multiplied, we move the decimal point 1 time(s) to the left (reducing the result by the factor of 10) to get the final result:
The solution is: 7,2
