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, 18 represents how many parts out of the whole. The denominator (the number below) shows how many parts make the whole, here it is 20. 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.
18/20 in decimals can be written as 0.9. It is a terminating decimal, meaning it does not repeat infinitely.
To get 18/20 in decimal, we will use the division method. Here, as 18 is smaller than 20, we will take the help of the decimal method, which will give us 0.9. Let's see the step-by-step breakdown of the process:
Step 1: Identify the numerator and denominator because the numerator (18) will be taken as the dividend and the denominator (20) will be taken as the divisor.
Step 2: Since 18 is smaller than 20, we know the result will be less than 1, so we place a decimal point in the quotient.
Step 3: Divide 18 by 20.
Step 4: Since 18 divided by 20 equals 0.9, and there is no remainder, we have a terminating decimal.
The answer for 18/20 as a decimal will be 0.9.
