Question

Round 2.71828 to the nearest tenth.

Answer 1

The decimal 2.71828 rounded to the nearest tenth is 2.7.

This is because, when you are rounding, you have to first look at the digit you are rounding, which is 7 in this case. Then, we have to go one space to the right. If the digit that is one space to the right is at least greater than 5, then we add one to the digit we are rounding. However, if it’s lower than 5, then we leave the digit alone and everything else to the right turns into a 0. In this case, the digit to the right of 7 is lower than 5, meaning that 2.7 stays and the everything to the right of 7 becomes a 0. Hence, the answer is 2.7
