Usage examples

1. Convert the fraction 3/8 to a decimal by dividing 3 by 8. The decimal equivalent of 3/8 is 0.375.
2. When adding decimal numbers, align the decimal points and then add the digits as if they were whole numbers. For example, to add 2.4 and 1.27, align the decimal points as 2.40 and 1.27, then add 2.40 + 1.27 = 3.67.
3. To multiply decimal numbers, multiply the numbers as if they were whole numbers, and then count the total number of decimal places in both numbers combined. For instance, to multiply 2.5 by 0.6, multiply 25 by 6 (ignoring the decimal points) to get 150, and since there is one decimal place in total (from 2.5 and 0.6), the answer is 0.15.
4. When converting a decimal to a fraction, write the decimal number divided by 1, followed by the appropriate power of 10 in the denominator. For example, 0.75 can be written as 75/100. Simplifying this fraction further gives 3/4.
5. The decimal system is a positional numeral system that uses the base of 10. It includes digits from 0 to 9, and the value of each digit depends on its position in the number. For instance, in the decimal number 536, the digit 5 represents 500, the digit 3 represents 30, and the digit 6 represents 6.
