how do u convert a decimal into a fraction
Solution
To convert a decimal into a fraction, you can follow these steps:
-
Identify the decimal part: Start by identifying the digits after the decimal point.
-
Count the decimal places: Determine how many digits are to the right of the decimal point. This will help you find the denominator of the fraction.
-
Write the decimal as a fraction: Write the decimal number as a fraction with the given decimal part as the numerator and a denominator based on the number of decimal places:
- If there is 1 decimal place, the denominator is 10.
- If there are 2 decimal places, the denominator is 100.
- If there are 3 decimal places, the denominator is 1000, and so on.
-
Simplify the fraction: Reduce the fraction to its simplest form by dividing both the numerator and the denominator by their greatest common divisor (GCD).
Example
Let's convert the decimal 0.75 into a fraction:
-
Identify the decimal part: 0.75
-
Count the decimal places: There are 2 decimal places.
-
Write as a fraction:
-
Simplify the fraction: The GCD of 75 and 100 is 25, so divide both numerator and denominator by 25:
So, 0.75 as a fraction is .
