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.

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.

Before multiplying, change any mixed numbers to improper fractions. Finally the division rule gives us Before multiplying, change any mixed numbers to improper fractions. Simply determine what power of 10 the decimal extends to, use that power of 10 as the denominator, enter each number to the right xxxomg the decimal point as the numerator, and simplify.

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. The calculator helps in finding value from multiple fractions operations. Solve problems with two, three, or more fractions and numbers in one expression. How do we solve fractions step by step?

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.

A conditional equation is true for only certain values of the literal numbers in it. Since dividing by zero is not allowed in mathematics, expressions such as are meaningless. Decimals decimal numbers enter with a decimal point. If you use mixed numbers, leave a space between the whole and fraction parts. Example 6 Solution Here our task is the same but a little more complex. In this example change. An identity is true for all values of the literal and arithmetical numbers in it. Here again, we needed to use both the addition rule and the division rule to solve the equation. Partial Fractions. 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. What fraction of the 26 alphabets did he use? Note that in each case only the numerator of the fraction is multiplied by the whole number.

.

In order to divide fractions, the fraction in the numerator is multiplied by the reciprocal of the fraction in the denominator. Here again, we needed to use both the addition rule and the division rule to solve the equation. Notice that the division rule does not allow us to divide by zero. Remember to always check your solution. Solve equations and inequalities Simplify expressions Factor polynomials Graph equations and inequalities Advanced solvers All solvers Tutorials. Which of these: A. We must multiply each term of the equation by a number that is divisible by both 3 and 5. 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. You may want to leave your answer as an improper fraction instead of a mixed number. Once again, we will rely on previous knowledge. Second Simplify by combining like terms on each side of the equation.
