MathPapa Toggle navigation. This is a tutorial on how to use the Algebra Calculatora step-by-step calculator for algebra.

Below are multiple fraction calculators capable of addition, subtraction, multiplication, division, simplification, and conversion between fractions and decimals. Fields above the solid black line represent the numerator, while fields below represent the denominator. In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and 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 3 8 , the numerator is 3, and the denominator is 8. A more illustrative example could involve a pie with 8 slices.

Unlike adding and subtracting integers such as 2 and 8, fractions require a common denominator to undergo these operations. An alternative method for finding a common denominator is to determine the least common multiple LCM for the denominators, then add or subtract the numerators as one would an integer. Here is an example evaluating the expression xy at the point 3,4 : xy 3,4. To complete an addition or subtraction problem, multiply the numerators and denominators of each fraction in the problem by whatever value will make the denominators 12, then add the numerators. To check an answer to a system of equations containing x and y, enter the two equations separated by a semicolon, followed by the sign and an ordered pair containing your x-value and y-value. If possible, the solution should be simplified. In the example above, the denominators were 4, 6, and 2. Since the answer is right, Algebra Calculator shows a green equals sign. MathPapa Toggle navigation. The most common fractional and decimal equivalents are listed below. Refer to the addition section as well as the equations below for clarification. The least common multiple is the first shared multiple of these three numbers.

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. Fraction subtraction is essentially the same as fraction addition. As such, fraction solutions are commonly expressed in their simplified forms. To evaluate an expression containing x, enter the expression you want to evaluate, followed by the sign and the value you want to plug in for x. Solving Equations First go to the Algebra Calculator main page. The reciprocal of the fraction 3 4 would therefore be 4 3. For example, looking at the number 0. Simply, the numerators and denominators of each fraction are multiplied, and the result forms a new numerator and denominator. The first multiple they all share is 12, so this is the least common multiple. To check an answer to a system of equations containing x and y, enter the two equations separated by a semicolon, followed by the sign and an ordered pair containing your x-value and y-value. A more illustrative example could involve a pie with 8 slices. If the fraction were instead 5 , the decimal would then be 0. To complete an addition or subtraction problem, multiply the numerators and denominators of each fraction in the problem by whatever value will make the denominators 12, then add the numerators.
