Key Concepts

Decimal Numbers

Decimals are a method for representing fractions or parts of a whole by using a decimal point to separate the whole number part from the fractional part. They are based on the powers of 10 and are a common way of expressing numbers that are not whole numbers.

Fractions

Fractions express the division of a whole into equal parts, represented by a numerator (the number of parts considered) and a denominator (the total number of equal parts). They provide an alternative representation to decimals, often used for exact arithmetic and analysis.

Conversion of Decimals to Fractions

Converting a decimal to a fraction involves using the place value of the decimal part. The number is expressed as a fraction with a denominator that is a power of 10 (depending on the number of digits after the decimal point) and then simplified to its simplest form.

Simplification

Simplification of a fraction is the process of reducing the numerator and the denominator to the smallest possible integers that maintain the same ratio. This is typically done by dividing both terms by their greatest common divisor.
