Understanding Rounding
Rounding is the process of adjusting the digits of a number to make it simpler while retaining its approximate value. The primary purpose of rounding is to make calculations easier and to provide a more manageable number for analysis or reporting. Rounding can be applied in various contexts, such as finance, statistics, and everyday life.
What Does Rounding to the Nearest Tenth Mean?
When we talk about rounding to the nearest tenth, we refer to the practice of rounding a decimal number to one decimal place. The tenths place is the first digit to the right of the decimal point. For example, in the number 3.67:
- The tenths place is 6.
- The hundredths place (the second digit to the right of the decimal) is 7.
To round 3.67 to the nearest tenth, we look at the hundredths place. Because 7 is greater than 5, we round up the tenths place from 6 to 7. Therefore, 3.67 rounded to the nearest tenth becomes 3.7.
The Rounding Process
Rounding to the nearest tenth follows a straightforward process. Here is a step-by-step guide:
1. Identify the Tenths and Hundredths Places:
- Locate the tenths place (first digit after the decimal).
- Locate the hundredths place (second digit after the decimal).
2. Determine Whether to Round Up or Down:
- If the digit in the hundredths place is 5 or greater, round up the tenths place by 1.
- If the digit in the hundredths place is less than 5, keep the tenths place the same.
3. Rewrite the Number:
- Eliminate all digits to the right of the tenths place.
- Write down the new rounded number.
Example of Rounding to the Nearest Tenth
Let’s consider a few examples to illustrate the rounding process:
- Example 1: Round 2.34 to the nearest tenth.
- Tenths: 3
- Hundredths: 4
- Since 4 < 5, we keep 3 the same. Thus, 2.34 rounds to 2.3.
- Example 2: Round 5.76 to the nearest tenth.
- Tenths: 7
- Hundredths: 6
- Since 6 > 5, we round up. Thus, 5.76 rounds to 5.8.
- Example 3: Round 9.85 to the nearest tenth.
- Tenths: 8
- Hundredths: 5
- Since 5 = 5, we round up. Thus, 9.85 rounds to 9.9.
