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. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5 8 as shown in the image to the right. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below. Unlike adding and subtracting integers such as 2 and 8, fractions require a common denominator to undergo these operations.

Just multiply the numerators and denominators of each fraction in the problem by the product of the denominators of all the other fractions not including its own respective denominator in the problem.

The solution of equations is the central theme of algebra. In this chapter we will study some techniques for solving equations having one variable. To accomplish this we will use the skills learned while manipulating the numbers and symbols of algebra as well as the operations on whole numbers, decimals, and fractions that you learned in arithmetics. Upon completing this section you should be able to: Classify an equation as conditional or an identity. Solve simple equations mentally. Determine if certain equations are equivalent. Finding the values that make a conditional equation true is one of the main objectives of this text.

The equation solver allows to solve equations with an unknown with calculation steps : linear equation, quadratic equation, logarithmic equation, differential equation. Equation calculator An equation is an algebraic equality involving one or more unknowns. Solving an equation is the same as determining that unknown or unknowns. The unknown is also called a variable. This equation calculator can solve equations with an unknown, the calculator can solve equations with variables on both sides and also equations with parentheses :.

Not so! The literal numbers in an equation are sometimes referred to as variables. The solution of equations is the central theme of algebra. Example 5 Solution See if you obtain the same solution by multiplying each side of the original equation by Are two equations equivalent? What number do we subtract 5 from to obtain 3? If the fraction were instead 5 , the decimal would then be 0. Unlike adding and subtracting, it is not necessary to compute a common denominator in order to multiply fractions. Many students think that when they have found the solution to an equation, the problem is finished. Converting from decimals to fractions is straightforward. To prepare to use the division rule for solving equations we must make note of the following process: We usually write 1x as x with the coefficient 1 understood. New Example. In this chapter we will study some techniques for solving equations having one variable.

Solve Practice Play. Game Central. Greatest Common Factor.

Example 4 Solution Keep in mind that we wish to obtain x alone on one side of the equation. Here our task is more involved. If each side of an equation is multiplied by the same nonzero number, the resulting equation is equivalent to the original equation. It is best to use the least of such numbers, which you will recall is the least common multiple. Example 13 If the legal requirements for room capacity require 3 cubic meters of air space per person, how many people can legally occupy a room that measures 6 meters wide, 8 meters long, and 3 meters high? Since the answer is right, Algebra Calculator shows a green equals sign. Solution The answer to the second question involves the techniques for solving equations that will be discussed in the next few sections. For example, looking at the number 0. Solve proportions. Solve some basic applied problems using the multiplication rule. Check this solution in the original equation. This would make the fraction , which simplifies to , since the greatest common factor between the numerator and denominator is 2.
