Solution - Long multiplication
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | thousands | hundreds | tens | ones |
| 8 | 7 | 5 | ||
| × | 5 | |||
2. Multiply the numbers using long multiplication method
Start by multiplying the ones digit (5) of the multiplier 5 by each digit of the multiplicand 875, from right to left.
Multiply the ones digit (5) of the multiplicator by the number in the ones place value:
5×5=25
Write 5 in the ones place.
Because the result is greater than 9, carry the 2 to the tens place.
| Place value | thousands | hundreds | tens | ones |
| 2 | ||||
| 8 | 7 | 5 | ||
| × | 5 | |||
| 5 |
Multiply the ones digit (5) of the multiplicator by the number in the tens place value and add the carried number (2):
5×7+2=37
Write 7 in the tens place.
Because the result is greater than 9, carry the 3 to the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 3 | 2 | |||
| 8 | 7 | 5 | ||
| × | 5 | |||
| 7 | 5 |
Multiply the ones digit (5) of the multiplicator by the number in the hundreds place value and add the carried number (3):
5×8+3=43
Write 3 in the hundreds place.
Because the result is greater than 9, carry the 4 to the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 4 | 3 | 2 | ||
| 8 | 7 | 5 | ||
| × | 5 | |||
| 4 | 3 | 7 | 5 |
The solution is: 4,375
