Are these 3 equations equal 2.02, 0.02, 0.03 ? show me 3 decimals that are equivalent

No those decimals are not equal because if you put them into fractuons it would be this :

2 2/100
2/100
3/100
which do not equal the same thing

Equal decimals are

0.3
0.30
0.300

Because
0.3= 3/10
0.30= 30/100 = 3/10
0.300= 300/1000 = 3/10

They all end up being 3/10 in fraction form...
