What is the ultimate goal when converting a decimal back to a percentage?

1. To multiply the decimal by 10

2. To keep it as a fraction

3. To express it as a whole number

4. To convert it to an equivalent percentage

The correct answer is: To convert it to an equivalent percentage

The ultimate goal when converting a decimal back to a percentage is to express the decimal as an equivalent percentage. This process involves taking the decimal value and multiplying it by 100, which shifts the decimal point two places to the right, and then adding the percent sign. For example, if you have a decimal like 0.75, multiplying by 100 gives you 75%, thus showing its equivalent percentage form. This method helps in understanding the relationship between decimals and percentages, allowing for easier comparisons and interpretations in various contexts, such as statistics, financial calculations, and everyday situations where percentages are frequently used.
