To write a decimal as a fraction in simplest form, put the decimal over its place value and reduce by dividing numerator and denominator by their greatest common divisor (GCD).
How do you write a decimal as a fraction?
Write the decimal as a fraction with the decimal number over its place value (10, 100, 1000, etc.), then simplify if needed.
Take 0.6, for instance. It becomes 6/10 because the 6 sits in the tenths place. Divide both top and bottom by 2 and you get 3/5. This trick works for any decimal with a clear place value.
How do you put a decimal in simplest form?
Convert the decimal to a fraction, then divide both the numerator and denominator by their greatest common divisor to reduce it.
- Turn the decimal into a fraction using its place value (e.g., 0.25 = 25/100).
- Find the GCD of the numerator and denominator.
- Divide both by the GCD to reach simplest form (e.g., 25 ÷ 25 = 1, 100 ÷ 25 = 4 → 1/4).
Doing this keeps the fraction in its lowest terms, which makes math easier down the road.
