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, numerator (number on the top) here, 18 represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 5. 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 that to the right represents the fractional part.
18/5 in decimals can be written as 3.6. It is a terminating decimal, meaning it does not repeat.
To get 18/5 in decimal, we will use the division method. Here, as 18 is larger than 5, we can divide directly. Let's see the step-by-step breakdown of the process:
Step 1: Identify the numerator and denominator because numerator (18) will be taken as dividend and denominator (5) will be taken as divisor.
Step 2: Divide 18 by 5.
Step 3: 5 goes into 18 three times (5 × 3 = 15).
Step 4: Subtract 15 from 18 to get the remainder, which is 3.
Step 5: Bring down a 0 to the remainder, making it 30.
Step 6: 5 goes into 30 exactly six times (5 × 6 = 30).
Step 7: Subtract 30 from 30, resulting in a remainder of 0.
The answer for 18/5 as a decimal is 3.6.
