What is 1.208 rounded to the nearest hundredth
rusak2 [61]

Answer:

The answer is 1.21.

Step-by-step explanation:

The hundredth digit in 1.208 is 0, so you have to look at the number after that to either round 0 up or down. The number after 0 is 8. Since 8 is bigger than 5, you round 0 up by 1.


I hope this was clear!
