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. 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. Multiplying all of the denominators ensures that the new denominator is certain to be a multiple of each individual denominator. The numerators also need to be multiplied by the appropriate factors to preserve the value of the fraction as a whole. This is arguably the simplest way to ensure that the fractions have a common denominator.

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.

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.

The solution or root is said to satisfy the equation. Why do we multiply both sides by 15? Solution The answer to the second question involves the techniques for solving equations that will be discussed in the next few sections. Solve an equation, inequality or a system. Here our thinking should proceed in this manner. Remember that when we multiply a whole number by a fraction, we use the rule We are now ready to solve an equation involving fractions. Step 2 Combine like terms on each side of the equation. The first multiple they all share is 12, so this is the least common multiple. Give the answer correct to two decimal places. If each term of an equation is multiplied by the same nonzero number, the resulting equation is equivalent to the original equation. 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. Upon completing this section you should be able to: Use the division rule to solve equations.

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.

Techniques for solving equations will involve processes for changing an equation to an equivalent equation. Keeping in mind our goal of obtaining x alone, we observe that since 3 has been subtracted from 2x, we add 3 to both sides of the equation. Partial Fractions. Example 4 Solution Keep in mind that we wish to obtain x alone on one side of the equation. A solution or root of an equation is the value of the variable or variables that make the equation a true statement. To solve an equation follow these steps: Step 1 Eliminate fractions by multiplying each term by the least common multiple of all denominators in the equation. Algebra Calculator can also evaluate expressions that contain variables x and y. We now come to the last of the four basic operations in developing our procedure for solving equations. A ratio is the quotient of two numbers. To evaluate an expression containing x and y, enter the expression you want to evaluate, followed by the sign and an ordered pair containing your x-value and y-value.
