Understanding Fractions and Percents

In mathematics, fractions and percents are two ways to represent a part of a whole. A fraction is a way to express a part of a whole as a ratio of two numbers, while a percent is a way to express a part of a whole as a ratio of the part to the whole, multiplied by 100. In this article, we will learn how to express the fraction $\frac{7}{8}$ as a percent.

Converting a Fraction to a Percent

To convert a fraction to a percent, we need to divide the numerator by the denominator and multiply the result by 100. In the case of the fraction $\frac{7}{8}$ , we can follow these steps:

Divide the numerator (7) by the denominator (8): $\frac{7}{8} = 0.875$
Multiply the result by 100: $0.875 \times 100 = 87.5\%$

Expressing the Result as a Percent Containing a Fraction

Now that we have the decimal equivalent of the fraction $\frac{7}{8}$ , we can express it as a percent containing a fraction. To do this, we need to convert the decimal to a fraction and then express it as a percent.

Convert the decimal (0.875) to a fraction: $0.875 = \frac{7}{8}$
Express the fraction as a percent: $\frac{7}{8} = 87.5\%$

Conclusion

In this article, we learned how to express the fraction $\frac{7}{8}$ as a percent. We followed the steps of dividing the numerator by the denominator, multiplying the result by 100, and then expressing the result as a percent containing a fraction. The final result is $\frac{7}{8} = 87.5\%$ .

Q: What is the difference between a fraction and a percent?

A: A fraction is a way to express a part of a whole as a ratio of two numbers, while a percent is a way to express a part of a whole as a ratio of the part to the whole, multiplied by 100.

Q: How do I convert a fraction to a percent?

A: To convert a fraction to a percent, you need to divide the numerator by the denominator and multiply the result by 100. For example, to convert the fraction $\frac{7}{8}$ to a percent, you would divide 7 by 8 and multiply the result by 100.

Q: What if the fraction has a decimal value?

A: If the fraction has a decimal value, you can convert it to a percent by multiplying the decimal value by 100. For example, if the fraction $\frac{7}{8}$ has a decimal value of 0.875, you can convert it to a percent by multiplying 0.875 by 100.

Q: Can I express a percent as a fraction?

A: Yes, you can express a percent as a fraction by dividing the percent value by 100 and simplifying the result. For example, to express the percent 87.5% as a fraction, you would divide 87.5 by 100 and simplify the result to get $\frac{7}{8}$ .

Q: What are some common fractions and their percent equivalents?

A: Here are some common fractions and their percent equivalents:

Fraction	Percent Equivalent
$\frac{1}{2}$	50%
$\frac{1}{4}$	25%
$\frac{3}{4}$	75%
$\frac{5}{8}$	62.5%
$\frac{7}{8}$	87.5%

Q: How do I simplify a fraction before converting it to a percent?

A: To simplify a fraction, you need to find the greatest common divisor (GCD) of the numerator and denominator and divide both numbers by the GCD. For example, to simplify the fraction $\frac{12}{16}$ , you would find the GCD of 12 and 16, which is 4, and divide both numbers by 4 to get $\frac{3}{4}$ .
