Question

How do you round to the nearest unit?

Answer 1

Hint: In this question, we take a decimal number and round it to the nearest unit. If the tenths value of a decimal number is equal to five or more than five then we increase the digit at one’s place by one and the tenths place value becomes zero. And if the tenths value of a decimal number is less than five then the digit at the one place remains the same but the tenths place value becomes zero.

Complete step by step solution:
In this question, the word round to the nearest unit is used. First, we know about the mean of the round to the nearest unit. If the given number $$x$$ is already an integer, then it cannot be rounded. Hence round to the nearest unit is applicable for decimal numbers.
There are some rules given below for rounding to the nearest unit.
If the tenths place value (the digit at the first decimal place) of a decimal number is equal to five or greater than five, then the digit at one’s place increases by one, and the tenths place value becomes zero.
If the tenths place value of a decimal number is less than five, then the digit at one’s place remains the same and the tenths place value becomes zero.
Let’s take an example, the decimal number is $$6.685$$, which is round to the nearest place.
Then,
We check the tenths place value. Tenths place value is $$6$$. It is greater than $$5$$. Then one’s place value increases by $$1$$ and the tenths place value becomes zero.
Then, the decimal number $$6.685$$ is round to the nearest unit is $$7$$.
Let’s take another example, the decimal number is $$4.499$$, which is round to the nearest place.
Then,
We check the tenths place value. Tenths place value is $$4$$. It is less than $$5$$. Then one’s place value remains the same and the tenths place value becomes zero.

Then, the decimal number $$4.499$$ is round to the nearest unit is $$4$$.

Note:
If you want to round to the nearest unit of a decimal number then first you check the tenths digit of a decimal number is greater than, equal, or less than $$5$$. If the tenths value of a decimal number is equal to five or more than five, then you increase the digit at one’s place by one, and the tenths place value becomes zero. And if the tenths value of a decimal number is less than five then the digit at the one place remains the same but the tenths place value becomes zero.
