To convert 78% to a decimal, divide by 100:
78% = 78 ÷ 100 = 0.78
Explanation:
Converting percentages to decimals is a fundamental math skill used in everyday life, from calculating discounts to understanding data in science or economics. A percentage is a way of expressing a number as a fraction of 100. The term “percent” literally means “per hundred,” so 78% means 78 out of every 100 parts.
To convert any percentage to a decimal, you divide the percentage value by 100. This is because percentages are based on 100 units. For 78%, you perform the following simple division: 78%=78100=0.7878\% = \frac{78}{100} = 0.78
This means that 78% is equivalent to the decimal 0.78.
An easier and quicker method, especially without a calculator, is to move the decimal point two places to the left. Since 78% is a whole number, place an imaginary decimal point after the number: 78. → Then, move it two places left:
78. → 0.78
This conversion is very helpful in real-life applications. For example, if you’re calculating 78% of a price, like 78% of $50, you can multiply the decimal version: 0.78×50=390.78 \times 50 = 39
So, 78% of $50 is $39.
Understanding how to convert percentages to decimals also helps in comparing values more easily, especially in spreadsheets, graphs, or financial statements.
In summary, converting 78% to a decimal means dividing 78 by 100, which equals 0.78. Always remember that a percent is just another way of saying “out of 100,” and moving the decimal two places to the left will instantly give you the decimal form.
