3.21 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:
Integer Part: 3
Fractional Part: 21
Our goal is to round it so we only have an integer part using the following rules:
If the first digit in the fractional part of 3.21 is less than 5 then we simply remove the fractional part to get the answer.
If the first digit in the fractional part of 3.21 is 5 or above, then we add 1 to the integer part and remove the fractional part to get the answer.
The first digit in the fractional part is 2 and 2 is less than 5. Therefore, we simply remove the fractional part to get 3.21 rounded to the nearest whole number as:
3 or 3.00
23.c. 16.3
In 16.27 the number next to tenths (2), is 7 and 7 is greater than 5, so it means we will add 1 into 2 that becomes 3, then the answer is 16.2 plus0.1 is 16.3.
