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, numerator (the number on the top) here, 12 represents how many parts out of the whole. The denominator (the number below) shows how many parts make the whole, here it is 36. A decimal is a way to represent a 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.
12/36 in decimals can be written as 0.3333... It is a recurring decimal, indicating it will repeat the same digit infinitely.
To get 12/36 in decimal, we will use the division method. Since 12 is smaller than 36, we will simplify the fraction first and then convert it to a decimal. Let's see the step-by-step breakdown of the process:
Step 1: Simplify the fraction 12/36. The greatest common divisor (GCD) of 12 and 36 is 12. Divide both the numerator and the denominator by 12. This gives us 1/3.
Step 2: Convert the simplified fraction 1/3 to a decimal. Here, as 1 is smaller than 3, we will use the decimal method, which will give us 0.3333...
Step 3: Identify the numerator and denominator because the numerator (1) will be taken as the dividend, and the denominator (3) will be taken as the divisor.
Step 4: As 1 is smaller than 3, it can't be divided. We will add 0 to the dividend, which will make 1 as 10, and add a decimal point in the quotient place.
Step 5: Now that it is 10, we can divide it by 3. Let's see how many times 3 makes 10.
Step 6: 10 is not a multiple of 3, so we will look for the nearest number. That is 3 × 3 = 9. We will write 3 in the quotient place, and subtracting 9 from 10 gives 1.
Step 7: Bring down another 0 in the dividend place, making 1 as 10, and then repeat the division process. The division process continues, and we do not get the remainder as 0. This process is called a recurring decimal.
The answer for 12/36 as a decimal will be 0.3333...
