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 (the number on the top), here 12, which represents how many parts out of the whole. The denominator (the number below) shows how many parts make the whole, here it is 45. A decimal is a way to represent a number that is not whole, using a decimal point (.) to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
12/45 in decimals can be written as 0.2666..... It is a recurring decimal, indicating it will repeat the same digit infinitely.
To convert 12/45 into a decimal, we will use the division method. Let's see a step-by-step breakdown of the process:
Step 1: Identify the numerator and denominator, because the numerator (12) will be taken as the dividend and the denominator (45) will be taken as the divisor.
Step 2: As 12 is smaller than 45, it can't be divided directly. We will use the decimal method, adding a decimal point in the quotient place and adding zeros to the dividend.
Step 3: Now, treat it as 120 divided by 45. Determine how many times 45 goes into 120.
Step 4: 45 goes into 120 twice (2 × 45 = 90). Write 2 in the quotient place, subtract 90 from 120, leaving 30.
Step 5: Bring down a 0 to make it 300. Divide 300 by 45, giving 6 (6 × 45 = 270). Write 6 in the quotient, subtract 270 from 300, leaving 30.
Step 6: Repeat the process by bringing down another 0, and dividing again, continuing the recurring sequence.
The answer for 12/45 as a decimal will be 0.2666......
