Answer: 1/4
Step-by-step explanation: Using the place value chart we can see that 0.25 is twenty-five hundredths which can be written as the fraction 25/100. Since 25/100 is not in lowest terms, we divide the numerator and denominator by the greatest common factor of 25 and 100 which is 25 to get 1/4.
Therefore, 0.25 is equivalent to the fraction 1/4.
