Rounding numbers is a common mathematical operation that is used to estimate a value. It is used to simplify a number and make calculations or comparisons easier. When rounding numbers, you can choose to round to the nearest whole number, tenth, hundredth, or any other place value. In this article, we will discuss how to round 7.2 to the nearest tenth.
What is Rounding?
Rounding is the process of simplifying a number by reducing its complexity. It is a way to make it easier to work with and understand. To round a number, you look at the digit to the right of the place value you are rounding to. If that digit is less than five, you round down. If that digit is greater than five, you round up. For example, if you are rounding to the nearest tenth, you would look at the digit to the right of the tenths place. If it is less than five, you would round down to the nearest tenth. If it is greater than five, you would round up.
How to Round 7.2 to the Nearest Tenth
To round 7.2 to the nearest tenth, you must first look at the digit to the right of the tenths place. In this case, it is a 2. Since this digit is less than five, you must round down. This means that 7.2 rounded to the nearest tenth is 7.1.
Rounding Other Numbers to the Nearest Tenth
The same process can be used to round other numbers to the nearest tenth. For example, if you wanted to round 8.5 to the nearest tenth, you would look at the digit to the right of the tenths place, which is a 5. Since this digit is greater than 5, you would round up. This means that 8.5 rounded to the nearest tenth is 8.6.
Rounding to Other Place Values
You can also use the same process to round to other place values. For example, if you wanted to round 7.26 to the nearest whole number, you would look at the digit to the right of the ones place. In this case, it is a 6. Since this digit is greater than 5, you would round up. This means that 7.26 rounded to the nearest whole number is 8.
Rounding numbers is a useful mathematical skill that can be used to simplify calculations or comparisons. To round a number, you must look at the digit to the right of the place value you are rounding to. If that digit is less than five, you round down. If that digit is greater than five, you round up. In this article, we discussed how to round 7.2 to the nearest tenth. We also discussed how to use the same process to round other numbers to the nearest tenth and to other place values.
