Yes a whole number is a number without a fraction or a decimal point.
When rounding 3.6 to one decimal point, you look at the digit in the second decimal place, which is 6. Since 6 is equal to or greater than 5, you round up the digit in the first decimal place. Therefore, 3.6 rounded to one decimal point is 3.7.
