Megoldás - Long multiplication
Lépésről lépésre magyarázat
1. Rewrite the numbers from top to bottom aligned to the right
| Helyiérték | egyesek | . | tizedek |
| 2 | , | 5 | |
| × | 0 | , | 6 |
| , |
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 2 decimal place(s). So once calculated, the result will be reduced by the factor of 100.
| Helyiérték | százasok | tízesek | egyesek |
| 2 | 5 | ||
| × | 6 | ||
2. Multiply the numbers using long multiplication method
Start by multiplying the egyesek digit (6) of the multiplier 6 by each digit of the multiplicand 25, from right to left.
Multiply the egyesek digit (6) of the multiplicator by the number in the egyesek place value:
6×5=30
Write 0 in the egyesek place.
Because the result is greater than 9, carry the 3 to the tízesek place.
| Helyiérték | százasok | tízesek | egyesek |
| 3 | |||
| 2 | 5 | ||
| × | 6 | ||
| 0 |
3. Add the partial products
Multiply the egyesek digit (6) of the multiplicator by the number in the tízesek place value and add the carried number (3):
6×2+3=15
Write 5 in the tízesek place.
Because the result is greater than 9, carry the 1 to the százasok place.
| Helyiérték | százasok | tízesek | egyesek |
| 1 | 3 | ||
| 2 | 5 | ||
| × | 6 | ||
| 1 | 5 | 0 |
Because we have 2 digit(s) to the right of the decimal point in the numbers that are being multiplied, we move the decimal point 2 time(s) to the left (reducing the result by the factor of 100) to get the final result:
The solution is: 1,5
