Understanding the Problem

When dealing with percentages, it's essential to understand that they represent a fraction of a whole. In this case, we're asked to find 55% of 140. To solve this problem, we need to multiply 140 by 0.55, which is equivalent to 55% expressed as a decimal.

Calculating 55% of 140

To calculate 55% of 140, we multiply 140 by 0.55.

result = 140 * 0.55
print(result)

This calculation will give us the result of 77.0.

Rounding to the Nearest Ten if Necessary

Since the result is 77.0, we need to determine if it's necessary to round to the nearest ten. In this case, the result is already a multiple of ten, so no rounding is necessary.

Why Rounding is Important

Rounding numbers to the nearest ten is essential in various mathematical and real-world applications. For instance, in finance, rounding numbers to the nearest ten can help simplify calculations and make it easier to understand large numbers. In statistics, rounding numbers to the nearest ten can help reduce the impact of minor variations in data.

When to Round to the Nearest Ten

Rounding to the nearest ten is typically necessary when dealing with large numbers or when the result of a calculation is not a multiple of ten. In such cases, rounding to the nearest ten can help simplify the number and make it easier to understand.

Examples of Rounding to the Nearest Ten

Here are a few examples of rounding to the nearest ten:

43.7 rounded to the nearest ten is 40
67.3 rounded to the nearest ten is 70
93.5 rounded to the nearest ten is 90

Conclusion

In conclusion, to find 55% of 140, we multiply 140 by 0.55, which gives us a result of 77.0. Since the result is already a multiple of ten, no rounding is necessary. However, in cases where the result is not a multiple of ten, rounding to the nearest ten can help simplify the number and make it easier to understand.
