Answer 2

Answer:

3.1

Step-by-Step explanation:

This is how to round 3.05 to the nearest tenth.

First note that 3.05 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: 05

To round 3.05 to nearest tenth means to round the numbers so you only have one digit in the fractional part.

We use the following rules to round 3.05 to the nearest tenth:

A) If the last digit in the fractional part of 3.05 is less than 5, then simply remove the last the digit of fractional part.

B) If the last digit in the fractional part of 3.05 is 5 or more and the first digit in the fractional part is less than 9, then add 1 to the first digit of the fractional part and remove the second digit.

C) If the last digit in the fractional part of 3.05 is 5 or more and the first digit in the fractional part is 9 then add 1 to the Integer part and make the fractional part 0.

With 3.05, rule B applies and the answer is:

3.1
