Converting decimal numbers to fractions is an essential skill in mathematics. Here, we'll explore three ways to convert the decimal 0.6875 to a fraction.
Why Convert Decimals to Fractions?
Before we dive into the methods, let's briefly discuss the importance of converting decimals to fractions. Fractions are often more intuitive and easier to work with, especially when dealing with mathematical operations like addition, subtraction, multiplication, and division. Moreover, fractions can provide a clearer understanding of the underlying mathematical concepts.
Method 1: Using Equivalent Ratios
One way to convert 0.6875 to a fraction is by using equivalent ratios. Since 0.6875 is equal to 6875/10000, we can simplify this fraction by finding the greatest common divisor (GCD) of the numerator and the denominator.
By dividing both the numerator and the denominator by their GCD, which is 125, we get:
6875 ÷ 125 = 55 10000 ÷ 125 = 80
So, 0.6875 is equal to 55/80.
Method 2: Using Fractional Notation
Another method to convert 0.6875 to a fraction is by using fractional notation. We can write 0.6875 as:
0.6875 = 6875/10000 = (6875 ÷ 100) / (10000 ÷ 100) = 68.75 / 100
Now, we can simplify this fraction by dividing both the numerator and the denominator by 25:
68.75 ÷ 25 = 2.75 100 ÷ 25 = 4
So, 0.6875 is equal to 2.75/4 = 55/80.
Method 3: Using a Calculator or Online Tool
The third method to convert 0.6875 to a fraction is by using a calculator or an online tool. There are many online tools and calculators available that can convert decimals to fractions in a matter of seconds.
By entering 0.6875 into an online fraction calculator, we get the result:
0.6875 = 55/80
