\nHow can you round to the nearest hundred?
\nAnswer:
\nTo the nearest hundred, about how many rocks does Donna have?
\nRound 350 to the nearest hundred.
\nOne Way<\/strong>
\nYou can use a number line.
\n![\"Envision](\"https:\/\/envisionmathanswerkey.com\/wp-content\/uploads\/2021\/04\/Envision-Math-3rd-Grade-Answer-Key-Topic-2.2-Rounding-2-and-3-Digit-Numbers-2.png\")
\nIf a number is halfway between, round to the greater number.
\n350 is halfway between 300 and 400, so 350 rounds to 400.<\/p>\n
\nYou can use place value.
\nFind the digit in the rounding place. Then look at the next digit to the right.

\nSo, 350 rounds to 400. Donna has about 400 rocks<\/p>\n
\nIf you round 350 to the nearest ten, would you still say that Donna has about 400 rocks? Why or why not?
