-1/5 as a Decimal

Answer

-1/5 in decimals can be written as -0.2. It is a terminating decimal, meaning it ends and does not repeat infinitely.

Explanation

To get -1/5 in decimal, we will use the division method. Here, as 1 is smaller than 5, we will take the help of the decimal method, which will give us -0.2. Let's see the step-by-step breakdown of the process:

Step 1: Identify the numerator and denominator because numerator (-1) will be taken as the dividend and denominator (5) will be taken as the divisor.

Step 2: As -1 is smaller than 5, it can't be divided directly; here, we will take the help of decimals. We will add 0 to the dividend, which will make -1 as -10 and add a decimal point in the quotient place.

Step 3: Now that it is -10, we can divide it by 5. Let's see how many times 5 makes -10.

Step 4: -10 is not a multiple of 5, so we will look for the nearest number that 5 × 2 = 10. We will write -2 in the quotient place, and subtracting 10 from -10 gives 0. The division process ends with a remainder of 0, indicating a terminating decimal.

The answer for -1/5 as a decimal will be -0.2.
