You can't convert a number with decimals (or a fraction) to a whole number, without losing precision. You can round it to the nearest number, or truncate it (just remove the decimals), but in any case, that won't be the same number (just the nearest integer, in case you choose to round it), so "2.8 as a whole number" really doesn't exist.

When rounding a number to the nearest whole number, you look at the decimal value immediately to the right of the decimal point. In this case, the number 27.53 has a decimal value of 0.53. Since 0.53 is greater than or equal to 0.5, you round the whole number up to 28. Therefore, 27.53 rounded to the nearest whole number is 28.
