Question

How do you round $ 0.682 $ to the nearest tenth?

Answer 1

Hint: We will start off by explaining the term quotient of a number. Then we will be mentioning the steps to solve such types of questions. Consider an unknown variable as $ n $ to further simplify and evaluate the terms. Also, we will mention some rules as well.

Complete step by step solution:
Rounding off a number means making a number simpler but keeping its value close to what it was. The results obtained are less accurate, but simpler to use. While rounding off decimals, the rules are: when you round to tenths means to leave one number after the decimal point. Rounding to hundredths means to leave two numbers after the decimal point.
We will start off by mentioning the base rules for rounding off the number.
The two conditions for rounding are based on the value of the digit immediately to the right of the cut off point.
Now if the digit to the right of the cut off point is $ 5 $ or more we round up by adding $ 1 $ to the digit to the left of the cut off point. If the digit to the right of the cut off point is less than $ 5 $ then do not change the digit to the left of the cut off point.
Here, we observe that $ 8 \geqslant 5 $ so we will round up giving $ \,0.7 $ to $ 1 $ decimal place
So, the correct answer is “ $ \,0.7 $ ”.

Note: While rounding off the numbers, make sure you follow all the rules and protocols that are based on the last number and also, if they are even or odd the rules will change accordingly. The rules will change while rounding off decimals and whole numbers.
