It is a simple question on decimal conversion. Firstly, we have to learn fractions and decimals. A fraction represents a part from the whole. It has two parts: the numerator (number on the top) here, 4 represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 20. A decimal is a way to represent a number that is not whole, using a (.) or a decimal point 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.
4/20 in decimals can be written as 0.2. It is a terminating decimal, which means it ends and does not repeat infinitely.
To convert 4/20 into a decimal, we will use the division method. Here, 4 is smaller than 20, so we will take the help of the decimal method, which will give us 0.2. Let's break down the process step by step:
Step 1: Identify the numerator and denominator because the numerator (4) will be taken as the dividend and the denominator (20) will be taken as the divisor.
Step 2: As 4 is smaller than 20, it can't be divided directly, so we will add a decimal point and a zero to the dividend, making it 40.
Step 3: Now that it is 40, we can divide it by 20. Let's see how many times 20 fits into 40.
Step 4: 40 is exactly twice 20, so we write 2 in the quotient place. So, 20 × 2 = 40, and subtracting 40 from 40 gives 0 as the remainder.
Step 5: Since the remainder is 0, the division process stops here. The answer for 4/20 as a decimal is 0.2.
