It is a simple question on decimal conversion. Firstly, we have to learn fractions and decimals. A fraction represents a part of the whole. It has two parts: the numerator (number on the top), here 1 represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 27. A decimal is a way to represent the number that is not whole, using a (.) or a decimal to separate the whole part from the fraction part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
1/27 in decimals can be written as 0.037037….. It is a recurring decimal, showing it will repeat the same digits infinitely.
To get 1/27 in decimal, we will use the division method. Here, as 1 is smaller than 27, we will take the help of the decimal method, which will give us 0.037037. 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 (27) will be taken as the divisor.
Step 2: As 1 is smaller than 27, it can't be divided. 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 cannot divide it by 27. We need to make this number larger by adding another zero, making it 100.
Step 4: 100 is not a multiple of 27, so we will look for the nearest number that is 27 × 3 = 81. We will write 3 in the quotient place and subtract 81 from 100, which gives us 19.
Step 5: Bring down another 0 in the dividend place, making it 190, and then repeat the division process.
Step 6: 190 divided by 27 gives 7, which is the nearest multiple (27 × 7 = 189), leaving a remainder of 1.
Step 7: Repeat the process by bringing down another 0. The division process continues, and we don't get the remainder as 0. This process is called a recurring decimal.
The answer for 1/27 as a decimal will be 0.037037……
