In mathematics, a decimal is a way of representing numbers that are not whole numbers or fractions

In mathematics, a decimal is a way of representing numbers that are not whole numbers or fractions. It is a system where numbers are expressed using a base of 10, with each digit representing a different power of 10.

The decimal system consists of three main components:
1. Whole number part: This is the part of the decimal that comes before the decimal point. It represents the number of whole units.
2. Decimal point: This is a punctuation mark that separates the whole number part from the fractional part.
3. Fractional part: This is the part of the decimal that comes after the decimal point. It represents a fraction of a whole unit.

For example, let’s look at the decimal number 3.456. The whole number part is 3, and the fractional part is 0.456. The decimal point separates these two parts.

Each digit in a decimal represents a power of 10:
– The rightmost digit represents the units place (10^0).
– The second rightmost digit represents the tens place (10^1).
– The third rightmost digit represents the hundreds place (10^2).
– And so on.

In the example above, the digit 4 represents the tens place, the digit 5 represents the tenths place (10^-1), the digit 6 represents the hundredths place (10^-2), and so on.

Decimals provide a way to represent both whole numbers and numbers less than one in a continuous manner. They also allow for accurate and precise representations of quantities that may not be easily expressed as fractions or whole numbers.
