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 (number on the top) here, 20 represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 100. 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.
20/100 in decimals can be written as 0.2. It is a terminating decimal, meaning it does not repeat indefinitely.
To get 20/100 in decimal, we will use the division method. Here, as 20 is smaller than 100, we will use the decimal method, which will give us 0.2.
Let's see the step-by-step breakdown of the process:
Step 1: Identify the numerator and denominator because the numerator (20) will be taken as the dividend and the denominator (100) will be taken as the divisor.
Step 2: As 20 is smaller than 100, it can't be divided directly. Here, we will take the help of decimals. We will add a decimal point in the quotient place.
Step 3: Now, multiply 100 by 0.2 to get 20, which means 100 goes into 20 as 0.2 times.
Step 4: The remainder is 0, confirming that 20/100 is a terminating decimal.
