3. Eric filled 3/4 buckets with sand. Then he filled
472 more. How many buckets of sand does he
have now?

Then 3/4 and 472 more is ...

Eric has 472 3/4 buckets filled with sand.

The problem statement here seems to be focused on the filled buckets, rather than the sand stockpile that Eric is working from.
