Expressing percentages as fractions is a fundamental concept in mathematics, and it's essential to understand how to convert between these two forms. In this article, we'll explore how to express 35 percent as a fraction in its simplest form.
The Importance of Converting Percentages to Fractions
Percentages and fractions are two different ways to represent parts of a whole. While percentages are often used in everyday applications, such as calculating discounts or tips, fractions are commonly used in mathematical and scientific contexts. Being able to convert between these two forms is crucial for problem-solving and critical thinking.
What is 35 Percent as a Fraction?
To convert 35 percent to a fraction, we need to remember that the word "percent" means "per 100." So, 35 percent is equivalent to 35/100. However, this fraction is not in its simplest form.
Simplifying the Fraction
To simplify the fraction 35/100, we need to find the greatest common divisor (GCD) of 35 and 100. The GCD is the largest number that divides both numbers without leaving a remainder.
Finding the Greatest Common Divisor
To find the GCD of 35 and 100, we can list the factors of each number:
- Factors of 35: 1, 5, 7, 35
- Factors of 100: 1, 2, 4, 5, 10, 20, 25, 50, 100
The largest number that appears in both lists is 5. Therefore, the GCD of 35 and 100 is 5.
Simplifying the Fraction
Now that we have found the GCD, we can simplify the fraction 35/100 by dividing both the numerator and the denominator by 5:
35 ÷ 5 = 7 100 ÷ 5 = 20
So, the simplified fraction is 7/20.
Real-World Applications
Expressing 35 percent as a fraction in its simplest form has many real-world applications. For example, in cooking, a recipe might call for 35% of a cup of flour. By converting this percentage to a fraction, we can easily measure out the correct amount.
Similarly, in finance, understanding how to convert percentages to fractions can help with calculations involving interest rates, investment returns, and tax rates.
Conclusion
In conclusion, expressing 35 percent as a fraction in its simplest form is a valuable skill that can be applied to various areas of mathematics and real-world problems. By understanding how to convert between percentages and fractions, we can become more proficient in our mathematical abilities and develop a stronger foundation for critical thinking and problem-solving.
