-1/2 as a Decimal

Answer

-1/2 in decimal can be written as -0.5. It is a terminating decimal, meaning it doesn't repeat or continue infinitely.

Explanation

To convert -1/2 into a decimal, we use the division method. Since -1 is smaller in absolute value than 2, we'll use the decimal method to find the result, which is -0.5. Let's see the step-by-step breakdown of the process:

Step 1: Identify the numerator and denominator. Here, the numerator (-1) will be taken as the dividend, and the denominator (2) will be taken as the divisor.

Step 2: As -1 is smaller in absolute value than 2, we can't divide it directly; we will use decimals. We consider -10 instead of -1 and place a decimal point in the quotient.

Step 3: Now that we have -10, we divide it by 2. Let's see how many times 2 fits into 10. Step 4: 10 divided by 2 equals 5. We place -0.5 in the quotient. The division yields a remainder of 0, confirming that the decimal is terminating.

The answer for -1/2 as a decimal is -0.5.
