How do i round 186.282?
adoni [48]

Well, first you need to decide what place you want to round it TO.

Example:  Round it to the nearest hundredth:

The next larger hundredth is  186.29 .
The next smaller hundredth is  186.28 .
Now look at it.
186.282  is closer to  186.28  than it is to  186.29 .
So the nearest hundredth is  186.28 .

-- When  186.282  is rounded to the nearest hundredth, it becomes  186.28 .

Similarly . . .
-- When  186.282  is rounded to the nearest tenth, it becomes  186.3 .
-- When  186.282  is rounded to the nearest whole number, it becomes  186 .
-- When  186.282  is rounded to the nearest ten, it becomes  190 .
-- When  186.282  is rounded to the nearest hundred, it becomes  200 .
-- When  186.282  is rounded to the nearest thousand or anything larger,
                                                                                       it becomes  zero.

I'm curious . . . where did this number come from ?

It happens to be one thousandth of the speed of light, in miles per hour.

Did it come up in science class, or did a science geek use it for
one of the problems in math ?

lawyer [7]
You should double the sugar as well, but first let us simplify the 2 2/3 to become 8/3, then double that to have 16/3,
Which is then can be simplified to 5 1/3
