How to solve fractions


A fraction is an expression of the part of an integer.</a>

Addition and subtraction of fractions become analogousThe same actions on integers when the fractions have the same denominators. Therefore, first of all, fractions are required to lead to a common denominator.

To perform operations of division and multiplication of fractions, it is not necessary to bring fractions to a common denominator.



If you need to multiply fractions on each other, you should multiply all the numerators separately and separately all the denominators.


If you need to split a fraction intoAnother, swap the numerator and denominator of the divisor (the fraction into which the first fraction is divided), and then perform the operation of multiplying the obtained fractions (see point 1).


In case you need to add or subtractFractions, you need to first know whether they have the same denominators. If so, the procedure of addition or subtraction is subtraction or addition of numerators of fractions, and the denominator remains the same. For example, 4 / 5-2 / 5 = 2/5.


To subtract or add fractions with differentDenominators, it is necessary to bring them to a common denominator. As a common denominator, the common multiple of the denominators of the original fractions is taken. It is simplest to find it by multiplying the denominators of fractions. Do it.


Multiply the numerator of each fraction by the denominators of all other fractions.


Now subtract or add the numbers obtained in the numerators, and assign the common denominator obtained in clause 4.
