Write 7 in the ones place.
| Place value | hundreds | tens | ones |
| 1 | 9 | 7 | |
| × | 1 | ||
| 7 |
Multiply the ones digit (1) of the multiplicator by the number in the tens place value:
1×9=9
Write 9 in the tens place.
| Place value | hundreds | tens | ones |
| 1 | 9 | 7 | |
| × | 1 | ||
| 9 | 7 |
Multiply the ones digit (1) of the multiplicator by the number in the hundreds place value:
1×1=1
Write 1 in the hundreds place.
| Place value | hundreds | tens | ones |
| 1 | 9 | 7 | |
