The 2nd and 3rd expressions are correct.
Step-by-step explanation:2nd Expression:4 × 100 + 0 × 10 + 3 × 1 + 0 × 1/10 + 8 × 1/100 =
Organization [(4 × 100) + (0 × 10) + (3 × 1) + (0 × 1/10) + (8 × 1/100)] =
Excluding Unnecessary Items [(4 × 100) + (3 × 1) + (8 × 1/100)] =
Simplifying [(400) + (3) + (0.08)]
=
Adding [403.08]
3rd Expression:Expression: 4 × 100 + 3 × 1 + 8 × 1/100
Organization [(4 × 100) + (3 × 1) + (8 × 1/100)] =
Simplifying [(400) + (3) + (0.08)] =
Adding [403.08]
This concludes that these two expressions are the only right ones; at least in that list.
