The correct answer and explanation is:
Correct Answer:
0.73 as a percentage is 73%
Explanation:
To convert a decimal number like 0.73 to a percentage, the basic idea is to express the decimal as a fraction out of one hundred. A percentage simply means “per hundred.” The word comes from the Latin “per centum,” which literally means “by the hundred.” So, whenever a decimal needs to be converted to a percentage, multiply it by 100 and then add the percent symbol.
For 0.73, multiply by 100:
0.73 × 100 = 73
So, 0.73 is equal to 73%. The process works for any decimal. For example, 0.5 becomes 50% because 0.5 × 100 = 50. The same method works for repeating decimals, smaller decimals, or larger decimals.
This process connects decimals, fractions, and percentages. The decimal 0.73 is the same as the fraction 73/100. In fraction form, this means there are 73 parts out of a possible 100, which directly matches the meaning of percent. Percentages are commonly used in daily life to describe discounts, grades, statistics, or data analysis. Knowing how to shift between decimals and percentages is important in school subjects like math and also in practical settings like shopping or finance.
Another way to check is to move the decimal point two places to the right. This is the same as multiplying by 100. For 0.73, moving the decimal two places turns it into 73. This visual trick helps when doing mental math. Finally, add the percent sign to show it is a percentage.
Being comfortable with these conversions builds confidence in working with numbers in different forms. Whether looking at tax rates, calculating interest, or figuring out tips, converting decimals to percentages is a core math skill that makes interpreting information clearer and more practical.
