Megoldás - Long multiplication
Lépésről lépésre magyarázat
1. Rewrite the numbers from top to bottom aligned to the right
| Helyiérték | tízesek | egyesek | . | tizedek |
| 2 | 4 | |||
| × | 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 | százasok | tízesek | egyesek |
| 2 | 4 | ||
| × | 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 24, from right to left.
Multiply the egyesek digit (8) of the multiplicator by the number in the egyesek place value:
8×4=32
Write 2 in the egyesek place.
Because the result is greater than 9, carry the 3 to the tízesek place.
| Helyiérték | százasok | tízesek | egyesek |
| 3 | |||
| 2 | 4 | ||
| × | 8 | ||
| 2 |
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 (3):
8×2+3=19
Write 9 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 | 4 | ||
| × | 8 | ||
| 1 | 9 | 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: 19,2
