Word math problems Worksheets Calculators. Fraction calculator. This fraction calculator performs basic and advanced fraction operations, expressions with fractions combined with integers, decimals, and mixed numbers. It also shows detailed step-by-step information about the fraction calculation procedure.

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.

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. A solution or root of an equation is the value of the variable or variables that make the equation a true statement. Many equations can be solved mentally. Ability to solve an equation mentally will depend on the ability to manipulate the numbers of arithmetic. The better you know the facts of multiplication and addition, the more adept you will be at mentally solving equations.

In the example above, the denominators were 4, 6, and 2. Fraction subtraction is essentially the same as fraction addition. Multiplying each side of the equation by 15, we obtain Why do we multiply both sides by 15?

This calculator is a free online math tool that writes a polynomial in factored form. The solver shows a complete step-by-step explanation. To find the factored form of a polynomial, this calculator employs the following methods:. This is a rare situation where the first two terms of a polynomial do not have a common factor, so we have to group the first and third terms together. The most common special case is the difference of two squares. First, we need to notice that the polynomial can be written as the difference of two perfect squares. The binomial we have here is the difference of two perfect squares, thus the calculation will be similar to the last one. The second special case of factoring is the Perfect Square Trinomial. In this case, the first and third terms are perfect squares.

Wolfram Alpha is a great tool for factoring, expanding or simplifying polynomials. It also multiplies, divides and finds the greatest common divisors of pairs of polynomials; determines values of polynomial roots; plots polynomials; finds partial fraction decompositions; and more.

Below is an example using this method. 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. You may want to leave your answer as an improper fraction instead of a mixed number. Many of the exercises in previous sections have required the use of more than one rule in the solution process. As such, fraction solutions are commonly expressed in their simplified forms. Note that in the example just using the addition rule does not solve the problem. See if you obtain the same solution by multiplying each side of the original equation by Example 4 Solve for x: 0. A more illustrative example could involve a pie with 8 slices. In general, the fractional form is more meaningful and useful. 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. We may do either of these first. From this, six pairs are blue, three pairs are brown, two are black, and two are white. Finding the values that make a conditional equation true is one of the main objectives of this text. Again, be careful in setting up the proportion.

We will also introduce ratio and proportion and use the multiplication rule to solve proportions. If each term of an equation is multiplied by the same nonzero number, the resulting equation is equivalent to the original equation. What fraction of the total amount was used? This fraction calculator performs basic and advanced fraction operations, expressions with fractions combined with integers, decimals, and mixed numbers. If we choose to first add 2x to both sides, we obtain We now add 2 to both sides. Example 4 Solve for x: 0. Andy gets Andy gets five out of 15 questions wrong in his math test. We should think in this manner:. Example 8. Knowing that the first decimal place represents 10 -1 , 5 10 can be converted to 0.
