Question

How are 4.730 and 4.73 eqivalent

Answer 1

4.730 and 4.73 are equivalent because 0 has no value therefore if 0 has no value and you take away the 0 than you get 4.73 and 4.73.

Answer 2

The zero means nothing, it's just being used as a placeholder, like .7 and 0.7 mean the same thing.

good luck, i hope this helps :)
