Rounding numbers is a fundamental skill in mathematics. It's used to simplify numbers and make them easier to work with. This article will walk you through how to round the number 43.6 to the nearest tenth. Understanding this process is crucial for various applications, from everyday calculations to more complex scientific work.

Understanding Decimal Places and Rounding

Before we tackle rounding 43.6, let's review the basics. The number 43.6 has two parts: the whole number part (43) and the decimal part (.6). The decimal part represents fractions of a whole. The first digit after the decimal point represents tenths, the second represents hundredths, and so on.

Rounding to the nearest tenth means we're aiming to express the number using only one digit after the decimal point. We look at the digit immediately to the right of the tenths place to determine whether to round up or down.

Rounding 43.6 to the Nearest Tenth

The number we're working with is 43.6. The digit in the tenths place is 6. The digit immediately to the right is in the hundredths place, but there is no digit there (it's implied to be a zero).

The Rule: If the digit to the right of the rounding place is 5 or greater, we round up. If it's less than 5, we round down.

Since there's an implied zero in the hundredths place (less than 5), we round down. This means the digit in the tenths place remains the same.

Therefore, 43.6 rounded to the nearest tenth is 43.6.

Illustrative Examples:

Let's look at a couple more examples to reinforce the concept:

• 43.62 rounded to the nearest tenth: The digit in the hundredths place (2) is less than 5, so we round down. The answer is 43.6.
• 43.67 rounded to the nearest tenth: The digit in the hundredths place (7) is greater than or equal to 5, so we round up. The answer is 43.7.

Conclusion

Rounding numbers is a valuable mathematical skill. In this case, 43.6 rounded to the nearest tenth remains 43.6 because the digit in the hundredths place is less than 5. Remember the simple rule: 5 or greater, round up; less than 5, round down. This straightforward process simplifies numbers while maintaining a reasonable level of accuracy.
