What number would make the expression below true-
( ) 38 rounds to 300

She got it correct, the answer is 3, but she guessed.  Can someone explain to us how the answer is figured out.

Best Answer!

what's this?
from a fellow member
The ( ) is where you are putting the digit to make a 3 digit number.
When rounding a 3 digit number, you look at the last 2 digits.
if they are 01-49 you round down to the nearest 100
if they are 50-99 you round up to the nearest 100
Example: 338  rounds to 300 because 38 is less than 50.
