Penyelesaian - Long multiplication
Penjelasan langkah demi langkah
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | tens | ones | . | tenths | hundredths |
| 4 | 3 | . | 9 | 6 | |
| × | 2 | ||||
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.
| Place value | thousands | hundreds | tens | ones |
| 4 | 3 | 9 | 6 | |
| × | 2 | |||
2. Multiply the numbers using long multiplication method
Start by multiplying the ones digit (2) of the multiplier 2 by each digit of the multiplicand 4,396, from right to left.
Multiply the ones digit (2) of the multiplicator by the number in the ones place value:
2×6=12
Write 2 in the ones place.
Because the result is greater than 9, carry the 1 to the tens place.
| Place value | thousands | hundreds | tens | ones |
| 1 | ||||
| 4 | 3 | 9 | 6 | |
| × | 2 | |||
| 2 |
Multiply the ones digit (2) of the multiplicator by the number in the tens place value and add the carried number (1):
2×9+1=19
Write 9 in the tens place.
Because the result is greater than 9, carry the 1 to the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 1 | 1 | |||
| 4 | 3 | 9 | 6 | |
| × | 2 | |||
| 9 | 2 |
Multiply the ones digit (2) of the multiplicator by the number in the hundreds place value and add the carried number (1):
2×3+1=7
Write 7 in the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 1 | 1 | |||
| 4 | 3 | 9 | 6 | |
| × | 2 | |||
| 7 | 9 | 2 |
Multiply the ones digit (2) of the multiplicator by the number in the thousands place value:
2×4=8
Write 8 in the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 1 | 1 | |||
| 4 | 3 | 9 | 6 | |
| × | 2 | |||
| 8 | 7 | 9 | 2 |
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: 87.92
