-1/20 as a Decimal

Answer

-1/20 in decimals can be written as -0.05.

Explanation

To convert -1/20 to a decimal, we will use the division method. Here, as -1 is smaller than 20, the decimal method will give us -0.05. Let's see the step-by-step breakdown of the process:

Step 1: Identify the numerator and denominator because the numerator (-1) will be taken as the dividend, and the denominator (20) will be taken as the divisor.

Step 2: As -1 is smaller than 20, it can't be divided directly to give a whole number, so we use the decimal method. We will add 0 to the dividend, making -1 into -10, and add a decimal point in the quotient place.

Step 3: Now that it is -10, we can divide it by 20. Let's see how many times 20 fits into 10.

Step 4: 10 is not a multiple of 20, so we will look for the nearest number. Since 20 cannot fit into 10 at all, we consider 20 × 0 = 0.

Step 5: Bring down another 0 in the dividend place, making it -100, and then divide by 20, which results in -5. The division process results in a terminating decimal.

The answer for -1/20 as a decimal will be -0.05.
