round 907.457 to the nearest tens place.
? need help with this one please

907.457

The ten's place is the 4, which I have colored red.

So the answer will be one of these

1.    907.4 if rounded DOWN
2.    907.5 if rounded UP.

How to tell whether to round UP or round DOWN.

Look at the digit just to the right of the ten's place,
that is the first one you are not going to include in your
final answer.

If it is LESS THAN 5, round DOWN
If it is 5 or MORE, round UP

The digit just to the right of the 4 is 5, so we round UP,
making the answer 907.5
