1.32 to the nearest tenths
The Correct Answer and Explanation is:
To round the number 1.32 to the nearest tenth, follow these steps:
1. Identify the tenths place:
- The tenths place is the first digit to the right of the decimal point. In the number 1.32, the digit in the tenths place is 3.
2. Look at the digit in the hundredths place:
- The hundredths place is the second digit to the right of the decimal point. In the number 1.32, the digit in the hundredths place is 2.
3. Apply rounding rules:
- The rounding rule for decimal numbers is:
- If the digit in the next place (the hundredths place in this case) is 5 or greater, round the tenths place up by one.
- If the digit in the next place is less than 5, leave the tenths place unchanged.
In this case:
- The digit in the hundredths place is 2, which is less than 5.
4. Round the number:
- Since the hundredths place is less than 5, you leave the tenths place unchanged.
- The tenths place remains 3.
Thus, 1.32 rounded to the nearest tenth is 1.3.
Explanation:
Rounding is a common mathematical process used to simplify numbers. When you round to the nearest tenth, you focus on the digit in the tenths place and consider the next digit (in the hundredths place) to decide whether to round up or leave it as is. In this case, the hundredths digit (2) was less than 5, so the tenths digit (3) remained unchanged.
Rounding is useful in many practical situations, especially when working with measurements or when you want to simplify a number for easier comprehension or calculation. For example, when calculating prices in stores or estimating distances, rounding to a specific place value makes numbers easier to work with.
