One method for finding a common denominator involves multiplying the numerators and denominators of all of the fractions involved by the product of the denominators of each fraction. All this is possible thanks to the income generated by advertising and subscriptions.

Simply determine what power of 10 the decimal extends to, use that power of 10 as the denominator, enter each number to the right of the decimal point as the numerator, and simplify. Fields above the solid black line represent the numerator, while fields below represent the denominator.
Use this calculator if the numerators or denominators are very big integers.
In mathematics, a fraction is a number that represents a part of a whole.
It does, however, require the understanding that each decimal place to the right of the decimal point represents a power of 10; the first decimal place being 101, the second 102, the third 103, and so on. This is arguably the simplest way to ensure that the fractions have a common denominator.
Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined.
ab / cd = ab × dc = adbc
EX: 34 / 16 = 34 × 61 = 184 = 92
It is often easier to work with simplified fractions. Multiplying all of the denominators ensures that the new denominator is certain to be a multiple of each individual denominator.
This would make the fraction 123410000, which simplifies to 6175000, since the greatest common factor between the numerator and denominator is 2.
Similarly, fractions with denominators that are powers of 10 (or can be converted to powers of 10) can be translated to decimal form using the same principles. Read more

There are several different ways to do this in German. 220440 for example, is more cumbersome than 12. If the fraction were instead 5100, the decimal would then be 0.05, and so on.
