Answer: 0.5
Step-by-step explanation: In order to write 1/2 as a decimal, we need to find a fraction equivalent to 1/2 with a denominator of 10.
Notice that if we multiply the numerator and denominator of 1/2 by 5, we get the equivalent fraction 5/10 which we can now write as a decimal.
Since the tenths place is one place to the right of the decimal, we can write 5/10 as the decimal 0.5.
Therefore, 1/2 can be written as the decimal 0.5.
