Study Notes
-
To convert a terminating decimal to a fraction, express the decimal as a numerator over a denominator.
-
The denominator should be a power of 10 (10, 100, 1000, etc.). The power of 10 corresponds to the number of decimal places.
-
Example:
- 0.5 is equivalent to 5/10
-
Simplify the resulting fraction to its lowest terms. This involves finding the greatest common divisor (GCD) of the numerator and denominator and dividing both by it.
- In this case, 5/10 simplifies to 1/2
-
Example:
- 0.25 = 25/100; simplified to 1/4
- 0.125 = 125/1000; simplified to 1/8
- 0.7 = 7/10
- 0.375 = 375/1000; simplified to 3/8
General Procedure
- Count the number of digits after the decimal point. This determines the power of 10 in the denominator.
- Write the digits after the decimal point as the numerator.
- Write the denominator as 10 raised to the power of the number of decimal places.
- Simplify the fraction to the lowest terms by dividing the numerator and the denominator by their greatest common divisor (GCD).
Examples with Detailed Steps
-
Convert 0.3 to a fraction:
- The decimal has one digit after the decimal point, so the denominator will be 10.
- The numerator is 3.
- The fraction is 3/10.
- The fraction is already in its simplest form.
-
Convert 0.12 to a fraction:
- The decimal has two digits after the decimal point, so the denominator will be 100.
- The numerator is 12.
- The fraction is 12/100.
- Simplifying, the GCD of 12 and 100 is 4. Dividing both by 4 gives the simplified fraction of 3/25.
-
Convert 0.16 to a fraction:
- The decimal has two digits after the decimal place.
- Construct a fraction with 16 in the numerator and 100 in the denominator (16/100).
- Find the GCD of 16 and 100. The GCD is 4.
- Divide both the numerator and denominator by the GCD: 16/4 = 4 and 100/4 = 25. This makes the converted fraction 4/25
Important Considerations
- Always simplify the fraction to its lowest terms. Failure to do so will result in an answer that isn’t expressed in its simplest form.
- The process is consistent for any terminating decimal.
- Write the fraction in its simplest form means writing the fraction with the lowest possible numerator and denominator values.
