What is 62.83 rounded to the nearest whole unit

62.83 rounded to the nearest whole unit is 63. 

If the decimal number is less than .5, it gets rounded down. If it's above .5 (i.e. .83) then it gets rounded up.

We round up or down depending on the value of the next
digit.

If the tenths place digit is less than 5, round down.

If the tenths place digit is greater than or equal to 5, we
would round up.

62.83 rounded to the nearest whole unit is 63.

Hope I helped!

I'm just guessing, but my answer would c. 0 to 300.
