What is 0.5 written as a fraction
0.5 written as a fraction is 1/2.
To write 0.5 as a fraction, we can use the fact that the decimal represents the ratio of the given number to a power of 10.
0.5 can be written as 5/10, but we can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 5 and 10 is 5.
By dividing both the numerator and denominator by 5, we get:
5/10 = (5 ÷ 5) / (10 ÷ 5) = 1/2
Therefore, 0.5 written as a fraction is equivalent to 1/2.
