Answer 1

Heya!

Here's your answer -

1. 125 × 6753 × 8
=> (125 × 8) × 6753
=> 1000 × 6753
=> 67,53,000

2. 105 × 673
=> 673 × (100 + 5)
=> 673 × 100 + 673 × 5
=> 67300 + 3365
=> 70665

3. 1297 ×97 + 1297 × 3
=> 1297 × (97+3)
=> 1297 × 100
=> 129700

4. 1863 × 105 - 1869 × 5 (no property can be used here)
=> 186270

5. 1008 × 225
=> 225 × (1000 + 8)
=> 225 × 1000 + 225 × 8
=> 225000 + 1800
=> 226800

Hope it helps! ^^
