Introduction
Decimal numbers can be converted into fractions to make it easier to compare, add, subtract, multiply, and divide them with other fractions. In this article, we will explain how to simplify 8.75 into a fraction and give you tips on how to convert other decimal numbers into fractions.
Understanding Decimals and Fractions
What are Decimals?
Decimals are a way to represent numbers that are not whole numbers. They are based on powers of 10, with each digit in the decimal representing a different power of 10. The first digit after the decimal point represents tenths, the second digit represents hundredths, the third digit represents thousandths, and so on.
What are Fractions?
Fractions are numbers that represent a part of a whole. They are represented by a numerator, which is the top number, and a denominator, which is the bottom number. The denominator represents the total number of equal parts the whole is divided into, while the numerator represents the number of parts being considered.
Simplifying 8.75 as a Fraction
To simplify 8.75 as a fraction, we need to convert the decimal into a fraction. Here are the steps to do it:
- Write down the decimal divided by 1: 8.75/1
- Multiply the top and bottom of the fraction by 100 to get rid of the decimal point: 875/100
- Simplify the fraction by finding the greatest common factor of the numerator and denominator, which is 25: 875/25 = 35/4
Therefore, 8.75 as a fraction in its simplest form is 35/4.
Tips for Converting Decimals into Fractions
1. Identify the Place Value
To convert a decimal into a fraction, it is important to identify the place value of each digit after the decimal point. For example, in 8.75, the 7 is in the tenths place and the 5 is in the hundredths place.
2. Multiply by a Power of 10
Once you have identified the place value, you need to multiply the decimal by a power of 10 to move the digits to the left until they are whole numbers. For example, to convert 8.75 into a fraction, we multiplied it by 100.
3. Simplify the Fraction
Finally, simplify the fraction by finding the greatest common factor of the numerator and denominator and dividing both by it. This will give you the fraction in its simplest form.
Conclusion
Converting decimals into fractions is a simple process that can make it easier to work with numbers in various mathematical operations. Remember to identify the place value, multiply by a power of 10, and simplify the fraction to get the answer in its simplest form.
