Let's solve the rounding problems step by step. We'll follow the standard rules for rounding:
-
To the nearest ten: Look at the
ones digit (the last digit). If it is 5 or more, round up; if less than 5, round down.
-
To the nearest hundred: Look at the
tens digit. If it is 5 or more, round up; otherwise, round down.
-
To the nearest thousand: Look at the
hundreds digit. If it is 5 or more, round up; otherwise, round down.
