## How to Convert Decimal to Fraction

Converting a decimal to a fraction requires that you understand the relationship between a decimal point and its fractional representation. Here are the steps to follow.

Step 1: Count the number of decimal places after the decimal point. Let n represent the number of decimal places.

Step 2: Write the decimal number as a fraction by placing the decimal number over a power of 10. For example, if there is one decimal place $n = 1$, the fraction is written as the decimal number divided by 10.

Step 3: Simplify the fraction to its lowest form.

For example:

Convert 0.75 to a fraction.

• The number of decimal places n = 2.

• Write the decimal as a fraction, which becomes 0.75/1.

• Simplify the Fraction. Remove the decimals by multiplying the numerator and denominator by the power of 10, which is 100 in this case$two decimal places$.

0.75/1 x $100/100$ = $0.75 * 100$ / $1 * 100$ = 75/100

• Simplify 75/100 further by dividing the numerator and the denominator with the largest number that can evenly divide both numbers.

In this case, the GCD $greatest common divisor$ of 75 and 100 is 25.

$75 ÷ 25$ / $100 ÷ 25$ = 3/4

## Converting Recurring Decimals to Fractions

Converting recurring decimals, which have repeating patterns, is slightly different.

Step 1: Create an equation where '𝓍' equals the recurring decimal.  For example, 0.454545… 𝓍 = 0.454545…

Step 2: Eliminate the recurring digits by creating a second equation with the same recurring part. Since there are two recurring decimal places, you must find a power of 10 that allows the recurring part to appear at the same place value.

So, the second equation is 100𝓍 = 45.4545…

Subtract the second equation from the first to remove the recurring part:

100𝓍 - 𝓍 = 45.4545... - 0.4545…

This gives us 99𝓍 = 45.

Step 4: Solve for '𝓍' by dividing both sides by 99 to get 𝓍 = 45/99.

Step 4: Simplify the fraction to its lowest form using the GCD of 45 and 99$it’s 9$, which gives us 5/11.

## Converting Negative Decimals to Fractions

1. Remove the negative sign from the decimal.

2. Convert the positive value to a fraction.

3. Reapply the negative sign to the fraction.

FAQs

1. What is the difference between terminating and recurring decimals?

Terminating has a finite number of decimal places $e.g., 0.25$, while recurring decimals have a repeating pattern $e.g., 0.333...$.
