How do you round 264 and 194 and 34

264 goes down to 260 ( the 4 rounds down)
194 goes down to 190
34 goes down to 30

If a number ends in a five or higher, you will round up. If a number is 4 or lower you will round down.
example:
•35 you would round up to 40
•33 you would round down to 30

264 ends in a four, therefore you should round down to 260.

194 also ends in a four, you should then round down to 190.

34 ends in a four, you would round down to 30.

With a continuous thought process.
