When we compare decimals, it also helps to remember that some numbers may look different, but are in fact equivalent. While $0.3$0.3 and $0.30$0.30 may look different, they have the same value. We can see this if we use a place value table:
| Ones | . | Tenths | Hundredths |
|---|---|---|---|
| $0$0 | . | $3$3 | |
| $0$0 | . | $3$3 | $0$0 |
