Simplify Conversions Now →Why are These Conversions Important?
- Real-World Applications: From calculating sales discounts to understanding interest rates, percentages are everywhere. Knowing how they relate to fractions and decimals allows you to make informed decisions.
- Mathematical Proficiency: Many mathematical concepts build upon the understanding of fractions, decimals, and percentages.
- Problem Solving: Converting between these forms can simplify complex problems and make them easier to solve. For example, figuring out a tip might be easier to visualize as a decimal (15% = 0.15) while understanding a population statistic might be easier as a percentage.
How to Convert Between Fractions, Decimals, and Percentages
Here are the basic methods for converting between the three:
Fractions to Decimals
To convert a fraction to a decimal, divide the numerator (the top number) by the denominator (the bottom number). For example:
1⁄4 = 1 ÷ 4 = 0.25
Decimals to Percentages
To convert a decimal to a percentage, multiply the decimal by 100 and add the "%" symbol. For example:
0.25 = 0.25 × 100% = 25%
Percentages to Decimals
To convert a percentage to a decimal, divide the percentage by 100. For example:
25% = 25 ÷ 100 = 0.25
Decimals to Fractions
To convert a decimal to a fraction, write the decimal as a fraction with a denominator of 10, 100, 1000, etc., depending on the number of decimal places. Then, simplify the fraction if possible. For example:
0.75 = 75⁄100 = 3⁄4 (simplified by dividing both numerator and denominator by 25)
Fractions to Percentages
To convert a fraction to a percentage, first convert the fraction to a decimal (as described above), then convert the decimal to a percentage. For example:
3⁄5 = 3 ÷ 5 = 0.6 = 0.6 × 100% = 60%
Percentages to Fractions
To convert a percentage to a fraction, write the percentage as a fraction with a denominator of 100. Then, simplify the fraction if possible. For example:
80% = 80⁄100 = 4⁄5 (simplified by dividing both numerator and denominator by 20)
