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.

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.

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.

If the same quantity is subtracted from 4 x 3 5 x 2 sides of an equation, the resulting equation is equivalent to the original equation. Simply, the numerators and denominators of each fraction are multiplied, and the result forms a new numerator and denominator. Note that the division rule allows us to divide each term of an equation by any nonzero number and the resulting equation is equivalent to the original equation.

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.

Give the answer correct to two decimal places. An identity is true for all values of the literal and arithmetical numbers in it. The most common fractional and decimal equivalents are listed below. Now we must use the division rule. Give your answer to 2 decimal places. Multiplying each side of the equation by 15, we obtain Why do we multiply both sides by 15? I thus need to subtract Ax from both sides. The solution or root is said to satisfy the equation. Upon completing this section you should be able to: Use combinations of the various rules to solve more complex equations. In the example above, the denominators were 4, 6, and 2. Be careful; always do multiplication and division before addition and subtraction. In this chapter we will study some techniques for solving equations having one variable. 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.

A In a class, there are 15 girls and 30 boys. In other words - four fifths multiplied by two thirds is eight fifteenths. Here our task is more involved. What fraction of the class represents the boys? A quarter A quarter of the number 72 is: Fractions There are pupils in the school. Notice that the division rule does not allow us to divide by zero. We now proceed to the next operation in our goal of developing an orderly procedure for solving equations. To eliminate the fraction we need to multiply by a number that is divisible by the denominator. Solve some basic applied problems using the multiplication rule. To prepare to use the division rule for solving equations we must make note of the following process:. Below are multiple fraction calculators capable of addition, subtraction, multiplication, division, simplification, and conversion between fractions and decimals. It also shows detailed step-by-step information about the fraction calculation procedure. This would give us a coefficient of 1 for x.
