Have you ever encountered the decimal number 8.75 and wondered how to express it as a fraction? You’re not alone. Many people struggle with converting decimals to fractions, and the process can be particularly tricky when dealing with decimals that have more than two decimal places. Fortunately, with the right tools and knowledge, you can easily write 8.75 as a fraction. In this article, we’ll walk you through the steps to convert 8.75 to a fraction and explain the concepts behind the conversion.
Understanding Decimals and Fractions
Before we dive into the specifics of converting 8.75 to a fraction, it’s essential to understand what decimals and fractions are and how they relate to each other. A decimal is a way of expressing a number that includes a whole number and a fraction of a whole number. In contrast, a fraction represents a part of a whole number. Both decimals and fractions can be used to represent the same value, but they are written and expressed differently.
Writing 8.75 as a Fraction
To convert 8.75 to a fraction, we first need to understand what the decimal represents. The number 8.75 can be broken down into 8 and 75/100. We can simplify 75/100 by dividing both the numerator and denominator by the greatest common factor, which is 25. This gives us 3/4. Therefore, 8.75 can be written as the fraction 8 3/4.
Converting Improper Fractions to Mixed Numbers
The fraction 8 3/4 that we derived from 8.75 is a mixed number, which means it has both a whole number and a fraction component. In some cases, it may be more appropriate to express the fraction as an improper fraction, which means the numerator is greater than the denominator. To convert a mixed number to an improper fraction, we multiply the whole number by the denominator and then add the numerator. The result is then placed over the denominator. In the case of 8 3/4, the improper fraction is (8 * 4 + 3)/4, which equals 35/4.
Simplifying Fractions
Sometimes, it’s possible to simplify a fraction further once we’ve converted it from a decimal. To simplify a fraction, we need to find the greatest common factor of the numerator and denominator and divide both by that number. In the case of 35/4, the greatest common factor is 5, which when divided results in the simplified fraction 7/4.
Converting 8.75 to Other Forms
In addition to expressing 8.75 as a fraction, we can also write it as a percentage or a ratio. To convert a decimal to a percentage, we multiply by 100 and add the percent sign. In this case, 8.75 as a percentage is 875%. To express 8.75 as a ratio, we can write it in the form of x:y. To find x and y, we multiply both the numerator and denominator by the same factor to obtain whole numbers. In this case, 8.75 as a ratio is 35:4.
Real-Life Applications
Knowing how to convert decimals to fractions is essential in many areas of life, including cooking, construction, and finance. In cooking, for example, recipes often call for measurements in fractions, and understanding how to convert decimals to fractions can help you follow a recipe accurately. Similarly, in construction, measurements often need to be expressed in fractions, and knowing how to convert decimals to fractions is essential. In finance, decimals are often used to represent percentages.
