Answer:

The 2nd and 3rd expressions are correct.

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.
