In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator và a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. For example, in the fraction of

Addition:
Unlike adding & subtracting integers such as 2 và 8, fractions require a common denominator to lớn undergo these operations. One method for finding a common denominator involves multiplying the numerators and denominators of all of the fractions involved by the hàng hóa of the denominators of each fraction. Multiplying all of the denominators ensures that the new denominator is certain to lớn be a multiple of each individual denominator. The numerators also need to be multiplied by the appropriate factors to lớn preserve the value of the fraction as a whole. This is arguably the simplest way lớn ensure that the fractions have a common denominator. However, in most cases, the solutions to lớn these equations will not appear in simplified form (the provided dhn.edu.vn computes the simplification automatically). Below is an example using this method.

This process can be used for any number of fractions. Just multiply the numerators and denominators of each fraction in the problem by the sản phẩm of the denominators of all the other fractions (not including its own respective denominator) in the problem.

An alternative method for finding a common denominator is khổng lồ determine the least common multiple (LCM) for the denominators, then địa chỉ or subtract the numerators as one would an integer. Using the least common multiple can be more efficient and is more likely khổng lồ result in a fraction in simplified form. In the example above, the denominators were 4, 6, và 2. The least common multiple is the first shared multiple of these three numbers.

Multiples of 4: 4, 8, 12 |
Multiples of 6: 6, 12 |
The first multiple they all cốt truyện is 12, so this is the least common multiple. To complete an addition (or subtraction) problem, multiply the numerators & denominators of each fraction in the problem by whatever value will make the denominators 12, then add the numerators.

Multiplication:
Multiplying fractions is fairly straightforward. Unlike adding và subtracting, it is not necessary to compute a common denominator in order to lớn multiply fractions. Simply, the numerators & denominators of each fraction are multiplied, and the result forms a new numerator và denominator. If possible, the solution should be simplified. Refer to the equations below for clarification.

Converting between fractions & decimals:
Converting from decimals khổng lồ fractions is straightforward. It does, however, require the understanding that each decimal place khổng lồ the right of the decimal point represents a power nguồn of 10; the first decimal place being 101, the second 102, the third 103, and so on. Simply determine what power nguồn of 10 the decimal extends to, use that nguồn of 10 as the denominator, enter each number lớn the right of the decimal point as the numerator, & simplify. For example, looking at the number 0.1234, the number 4 is in the fourth decimal place, which constitutes 104, or 10,000. This would make the fraction

Similarly, fractions with denominators that are powers of 10 (or can be converted lớn powers of 10) can be translated lớn decimal form using the same principles. Take the fraction
