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.
