Big Number Fraction khovattuhoanthien.com

Use this khovattuhoanthien.com if the numerators or denominators are very big integers.

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

Addition:

Unlike adding và subtracting integers such as 2 and 8, fractions require a common denominator to undergo these operations. One method for finding a common denominator involves multiplying the numerators và denominators of all of the fractions involved by the sản phẩm of the denominators of each fraction. Multiplying all of the denominators ensures that the new denominator is certain lớn be a multiple of each individual denominator. The numerators also need to lớn be multiplied by the appropriate factors lớn preserve the value of the fraction as a whole. This is arguably the simplest way khổng lồ ensure that the fractions have a common denominator. However, in most cases, the solutions khổng lồ these equations will not appear in simplified form (the provided khovattuhoanthien.com 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 và 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 to lớn determine the least common multiple (LCM) for the denominators, then showroom or subtract the numerators as one would an integer. Using the least common multiple can be more efficient and is more likely to 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.

The first multiple they all nội dung is 12, so this is the least common multiple. Khổng lồ complete an addition (or subtraction) problem, multiply the numerators và denominators of each fraction in the problem by whatever value will make the denominators 12, then địa chỉ the numerators.

Subtraction:

Fraction subtraction is essentially the same as fraction addition. A common denominator is required for the operation to occur. Refer to lớn the addition section as well as the equations below for clarification.

Multiplication:

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

Division:

The process for dividing fractions is similar lớn that for multiplying fractions. In order to divide fractions, the fraction in the numerator is multiplied by the reciprocal of the fraction in the denominator. The reciprocal of a number a is simply

Simplification:

It is often easier lớn work with simplified fractions. As such, fraction solutions are commonly expressed in their simplified forms.

Converting between fractions & decimals:

Converting from decimals to lớn fractions is straightforward. It does, however, require the understanding that each decimal place khổng lồ the right of the decimal point represents a power of 10; the first decimal place being 101, the second 102, the third 103, & so on. Simply determine what nguồn of 10 the decimal extends to, use that power of 10 as the denominator, enter each number khổng lồ the right of the decimal point as the numerator, and 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 to powers of 10) can be translated lớn decimal size using the same principles. Take the fraction

Common Engineering Fraction lớn Decimal Conversions

In engineering, fractions are widely used to lớn describe the size of components such as pipes & bolts. The most common fractional và decimal equivalents are listed below.
