Answer:
3
Step-by-step explanation:
3 is a whole number and estimating from the tenth places the number is a 1 which means you go back to an 3 not an 4.
the answer is 3
Numbers 4 and below usually round down and numbers 5 and up will round up to the next number so in this case, the number is 1 so it rounds down to 3. I hope this makes sense.
