Understanding the Basics

In mathematics, converting fractions and mixed numbers to percentages is an essential skill that helps us express these values in a more familiar and understandable format. Percentages are a way of expressing a value as a fraction of 100. In this article, we will explore how to convert fractions and mixed numbers to percentages, using two examples: 110\frac{1}{10} and 1120\frac{11}{20}.

Converting 110\frac{1}{10} to a Percentage

To convert a fraction to a percentage, we need to divide the numerator by the denominator and multiply the result by 100. Let's apply this rule to the fraction 110\frac{1}{10}.

Step 1: Divide the Numerator by the Denominator

The numerator of the fraction is 1, and the denominator is 10. To divide 1 by 10, we get:

110=0.1\frac{1}{10} = 0.1

Step 2: Multiply the Result by 100

Now that we have the decimal equivalent of the fraction, we need to multiply it by 100 to convert it to a percentage.

0.1×100=10%0.1 \times 100 = 10\%

Therefore, the fraction 110\frac{1}{10} is equivalent to 10%.

Converting 1120\frac{11}{20} to a Percentage

Now, let's apply the same process to the fraction 1120\frac{11}{20}.

Step 1: Divide the Numerator by the Denominator

The numerator of the fraction is 11, and the denominator is 20. To divide 11 by 20, we get:

1120=0.55\frac{11}{20} = 0.55

Step 2: Multiply the Result by 100

Now that we have the decimal equivalent of the fraction, we need to multiply it by 100 to convert it to a percentage.

0.55×100=55%0.55 \times 100 = 55\%

Therefore, the fraction 1120\frac{11}{20} is equivalent to 55%.
