3.2 in fraction form is 16/5.
To convert 3.2 to a fraction, we can divide the number by 1 and then multiply the numerator and denominator by 10, since there is one decimal place:
3.2 = 3.2/1 = 32/10
We can then simplify the fraction by dividing both the numerator and denominator by 2:
32/10 = 16/5
So, 3.2 in fraction form is indeed 16/5.
Why Is It Important to Convert Decimals to Fractions?
Converting decimals to fractions is an essential skill in mathematics, as it allows us to represent numbers in a more precise and intuitive way. Fractions are often used in real-world applications, such as cooking, science, and engineering, where exact measurements are crucial.
For instance, in cooking, recipes often require exact measurements, such as 3/4 cup of flour or 1/2 teaspoon of salt. Converting decimals to fractions enables us to follow these recipes accurately and achieve the desired results.
How to Convert Decimals to Fractions: A Step-by-Step Guide
Converting decimals to fractions is a straightforward process that involves a few simple steps:
Step 1: Write the Decimal as a Fraction
To convert a decimal to a fraction, start by writing the decimal as a fraction with the number itself as the numerator and 1 as the denominator.
Example: 0.5 = 0.5/1
Step 2: Multiply the Numerator and Denominator by a Power of 10
Next, multiply the numerator and denominator by a power of 10 that matches the number of decimal places.
Example: 0.5 = 0.5/1 = 5/10 (since there is one decimal place)
Step 3: Simplify the Fraction (If Possible)
Finally, simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD).
Example: 5/10 = 1/2 (since the GCD of 5 and 10 is 5)
By following these steps, you can easily convert decimals to fractions and represent numbers in a more precise and intuitive way.
Common Decimals and Their Fractional Equivalents
Here are some common decimals and their fractional equivalents:
