Let's look into the two methods to write 1/2 as a decimal.

Explanation: 

Method 1: Writing 1/2 as a decimal using the division method

To convert any fraction to decimal form, we just need to divide its numerator by denominator.

Here, the fraction is 1/2 which means we need to perform 1 ÷ 2

This gives the answer as 0.5. So, 1/2 as a decimal is 0.5

Method 2: Writing 1/2 as a decimal by converting the denominator to powers of 10

Step 1: Find a number such that we can multiply by the denominator of the fraction to make it 10 or 100 or 1000 and so on.

Step 2: Multiply both numerator and denominator by that number to convert it into it's an equivalent fraction.

Step 3: Then write down just the numerator, putting the decimal point in the correct place, that is, one space from the right-hand side for every zero in the denominator.

1/2 = (1 × 5) / (2 × 5) = 5/10 = 0.5

Irrespective of the methods used, the answer to 1/2 as a decimal will always remain the same.
