Answer:
350 rounded to hundred is 400
460 rounded to hundred is 500
510 rounded to hundred is 500
Step-by-step explanation:
350 is between 300 and 400. Since it is up to half of the distance between 300 and 400, it is rounded to 400, otherwise it is rounded to 300.
460 is between 400 and 500. It is closer to 500, so it is rounded to 500
510 is between 500 and 600. It is closer to 500, so it is rounded to 500.
