Understanding Decimals and Fractions

Before diving into the conversion, let's refresh our understanding of decimals and fractions. A decimal is a way of writing a number that uses a decimal point to separate the whole number part from the fractional part. A fraction, on the other hand, represents a part of a whole, expressed as a ratio of two numbers (numerator and denominator).

Converting 0.32 to a Fraction: The Steps

Converting 0.32 into a fraction involves a few simple steps:

Write the decimal as a fraction over 1: This is our starting point. We write 0.32 as 0.32/1.
Multiply the numerator and denominator by 100: Since there are two digits after the decimal point, we multiply both the top and bottom by 100 (10 to the power of the number of decimal places). This moves the decimal point two places to the right. This gives us 32/100.
Simplify the fraction: Now, we need to simplify the fraction 32/100 to its lowest terms. We find the greatest common divisor (GCD) of 32 and 100. The GCD of 32 and 100 is 4. We divide both the numerator and the denominator by 4:

32 ÷ 4 = 8 100 ÷ 4 = 25

Therefore, the simplified fraction is 8/25.

Another Method: Using Place Value

We can also approach this using place value. The number 0.32 means 3 tenths and 2 hundredths. This can be written as:

(3/10) + (2/100)

To add these fractions, we need a common denominator, which is 100:

(30/100) + (2/100) = 32/100

Again, simplifying this fraction by dividing both numerator and denominator by their GCD (4) gives us 8/25.

Why is Simplifying Important?

Simplifying fractions is crucial because it gives us the most concise and accurate representation of the fraction. While 32/100 is technically correct, 8/25 is a simpler and more commonly used form.

Practice Problems

Try converting these decimals to fractions using the methods explained above:

(Solutions: 3/4, 3/5, 1/8)

Conclusion

Converting decimals to fractions is a fundamental skill in mathematics. By understanding the steps and practicing, you can confidently convert any decimal to its equivalent fraction. Remember, 0.32 as a fraction is 8/25. This simple conversion is crucial for various applications, from everyday calculations to more complex mathematical problems.
