What is 1/1000 as a decimal?

1/1000 as a decimalAnswer

 

1/1000 in decimals can be written as 0.001. It is a terminating decimal, meaning it does not repeat infinitely.

 

Explanation

 

To get 1/1000 in decimal form, we will use the division method. Here, as 1 is smaller than 1000, we will take the help of the decimal method, which will give us 0.001. 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 (1000) will be taken as the divisor.

 

Step 2: As 1 is smaller than 1000, it can't be divided without using decimals. We will add 0 to the dividend, making 1 as 10, then as 100, and finally as 1000, adding a decimal point in the quotient place.

 

Step 3: Now that it is 1000, we can divide it by 1000. 1000 divided by 1000 is 1.

 

Step 4: Write 0.001 in the quotient place as the decimal representation of 1/1000. The division process stops as we have no remainder, and this is called a terminating decimal.

 

The answer for 1/1000 as a decimal will be 0.001.
