1/81 as a Decimal

Answer 1/81 in decimals can be written as 0.012345679012345679... It is a recurring decimal, showing it will repeat the same sequence of digits infinitely. Explanation To get 1/81 in decimal, we will use division method. Here as 1 is smaller than 81 we will take help of the decimal method which will give us 0.012345679012345679. 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 (81) will be taken as the divisor. Step 2: As 1 is smaller than 81, it can't be divided, so 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 81. Since 10 is smaller, we bring down another 0, making it 100. Step 4: 81 goes into 100 once, so we write 1 in the quotient place and subtract 81 from 100, giving 19. Step 5: Bring down another 0 in the dividend place to make 190, then continue the division process. The division process continues, forming a repeating sequence of digits. This process is called a recurring decimal. The answer for 1/81 as a decimal will be 0.012345679012345679...
