Answer:

1 hundredth

Step-by-step explanation:

1 Hundredth because 3 tenths isn't 1 hundred, and it rounds down. So its 1 hundredth.

Answer: 31 hundredths

Explanation:
1 hundredth equals 0.01
3 tenths equals 0.30
Just add both together and get 0.31
Convert that to a hundredth
Get 31/100 as answer
