How do i round this number to the tenths place? also how do i know when to round or not when rounding or rounding to the tenths place?

0.2

Step-by-step explanation:

0.206349 to the nearest tenth's place is 0.2.

Notice that what follows this 2 is 06349, which is clearly less than 50000.

If this is the case, we simply drop the 06349; but if the digits following 2 are 50000 or more, we round up.

So, as before, 0.206349 to the nearest tenth's place is 0.2.

                0.250000 would become 0.3 after rounding up.

                 0.263149 would become 0.3 after rounding up.
