Round 287.9412 to the nearest tenth. do not write extra zeros

Heee! :D

Let's take a look at this

Hmmm 287.9412 huh?   Now what we need to remember is that when rounding up we can only do that if the number is 5 or above 5.  

We also need to know what place is the tenths place
287.9412
        ^ there you have it!

Now if we look at the number before it it's a 4 but that is less than 5 so we need to round it down... our answer would be (drumroll please :D)

287.9 !

I hope this helps! :D

Please vote me for Brainliest if there is a second answer!

Well, because it is not above 5 (for the second decimal place) you can leave the number as it is, only having one decimal place:

287.9

Hope this helps! :)
