Let’s solve each multiplication problem step by step. We’ll multiply the 3-digit number by the 2-digit number using standard multiplication (also called long multiplication). Remember: multiply by the ones digit first, then the tens digit, and add the results.

1. 485 × 34
First, multiply 485 × 4 = 1940
Then, multiply 485 × 30 = 14550 (because 3 is in the tens place)
Add them: 1940 + 14550 =
16490

2. 323 × 51
323 × 1 = 323
323 × 50 = 16150
Add: 323 + 16150 =
16473

3. 854 × 70
This is easy — just multiply 854 × 7 = 5978, then add a zero →
59780
---
4. 483 × 54
483 × 4 = 1932
483 × 50 = 24150
Add: 1932 + 24150 =
26082
