The Correct Answer and Explanation is:
To write the decimal 0.44 as a percentage, you multiply the decimal by 100 and add a percent sign (%).
The correct answer is 44%.
Here is a detailed explanation of the conversion process.
The term “percent” originates from the Latin phrase “per centum,” which means “per hundred.” Therefore, a percentage is a way of expressing a number as a fraction of 100. When you see a number like 50%, it means 50 out of 100, or the fraction 50/100.
There are two simple, related methods to convert a decimal into a percentage.
Method 1: Multiply by 100
The most direct way to perform the conversion is to multiply the decimal number by 100. This calculation scales the number to its “per hundred” equivalent. For the decimal 0.44, the calculation is:
0.44 × 100 = 44
After multiplying, you must add the percent symbol (%) to indicate that the number is now a percentage. This gives you the final answer of 44%. This method works for any decimal. For example, to convert 0.75 to a percentage, you would calculate 0.75 × 100 = 75, resulting in 75%.
Method 2: Move the Decimal Point
A quick and easy shortcut for multiplying by 100 is to simply move the decimal point two places to the right. In the number 0.44, the decimal point is located between the 0 and the first 4.
- Start with the decimal: 0.44
- Move the decimal point one place to the right: 4.4
- Move it a second place to the right: 44.
After moving the decimal point two places, the resulting number is 44. As with the first method, the final step is to add the percent sign, giving you 44%.
Both methods are based on the same mathematical principle and will always yield the same result. You can also think of the decimal 0.44 as the fraction 44/100, which by definition is 44 percent.
