Answer:
357,340
Step-by-step explanation:
Locate the tens place:
357,3<u>3</u>5 
Check the number to the right:
357,33<u>5 </u>
<u></u>
If the number is greater than or equal to 5, then we round up. If the number is less than or equal to 4, we round down. 
The number next to the tens place is a '5'. We round up. 
357,335 ≈ 357,340
Hope this helps.
