Many find converting decimals to fractions challenging. This article simplifies the process, demonstrating how to convert the decimal 0.91 into its fractional equivalent. We'll break it down into easy-to-follow steps.

Understanding Decimals and Fractions

Before we begin, let's review the basics. Decimals represent parts of a whole using a base-ten system. Fractions, on the other hand, represent parts of a whole using a numerator (the top number) and a denominator (the bottom number). The denominator indicates the total number of equal parts, and the numerator shows how many of those parts are being considered.

Converting 0.91 to a Fraction: A Step-by-Step Approach

Here's how to convert the decimal 0.91 into a fraction:

Step 1: Write the decimal as a fraction over 1.

This is our starting point. We write 0.91 as a fraction:

0.91/1

Step 2: Multiply both the numerator and the denominator by 100.

Because there are two digits after the decimal point (9 and 1), we multiply both the top and bottom by 100 (10 raised to the power of 2). This eliminates the decimal point:

(0.91 x 100) / (1 x 100) = 91/100

Step 3: Simplify the Fraction (if possible).

In this case, 91 and 100 don't share any common factors other than 1. Therefore, the fraction is already in its simplest form.

Therefore, 0.91 as a fraction is 91/100.

Why Multiply by 100?

We multiplied by 100 because there are two digits after the decimal point. If there were three digits, we'd multiply by 1000. The number of zeros in the multiplier matches the number of digits after the decimal. This method ensures the decimal is eliminated, resulting in a whole number numerator.

More Examples: Converting Decimals to Fractions

Let's practice with a few more examples:

• 0.5: 0.5/1 -> (0.5 x 10) / (1 x 10) = 5/10 = 1/2
• 0.25: 0.25/1 -> (0.25 x 100) / (1 x 100) = 25/100 = 1/4
• 0.7: 0.7/1 -> (0.7 x 10) / (1 x 10) = 7/10
• 0.125: 0.125/1 -> (0.125 x 1000) / (1 x 1000) = 125/1000 = 1/8

Key Takeaways

Converting decimals to fractions is straightforward. Remember these key steps:

• Write the decimal over 1.
• Multiply the numerator and denominator by a power of 10 to eliminate the decimal. (The power of 10 is determined by the number of digits after the decimal point.)
• Simplify the fraction to its lowest terms.

By following these steps, you can confidently convert any decimal number into its fractional equivalent. Practice makes perfect!
