Given the value:
7.82
Round to the nearest tenth.
Solution:
In rounding numbers, it must be taken to note that if the number is greater than or equal to 5 then the succeeding number will be added by 1, hence if the number is less than 5, then the succeeding number will remain the same.
Since we are asked to round to round to the nearest tenth, we must determine first where tenth is. The number places are as follow in an ascending order: Ones/units, tens, hundreds, thousands, ten thousands, hundred thousands, millions, hundred millions, and so on.
For decimals, the number places starts with; tenths, hundredths, thousandths, ten thousandths, hundred thousandths, and so on.
8 is located in the tenths place and before 8 we have 2, which is less than 4, therefore we will retain the value of 8 as it is.
= 7.82
= 7.8
Final answer:
= 7.8
