You first divide 1 by 2. This is near impossible. So the first figure is 0. Then adding 0 to 1 makes it 10. Then you divide 10 by 2. It gives 5. Thus, the final answer is 0.5.
The decimal 0.25 represents the fraction 25/100. Decimal fractions always have a denominator based on a power of 10. We know that 5/10 is equivalent to 1/2 since 1/2 times 5/5 is 5/10. Therefore, the decimal 0.5 is equivalent to 1/2 or 2/4, etc.
