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, x 5 9 3. Upon completing this section you should be able to: Classify an equation as conditional or an identity.

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.

In order to divide fractions, the fraction in the numerator is multiplied by the reciprocal of the fraction in the denominator. Example 7. To solve for x we first write the proportion:. Therefore we could divide each side of the equation by 5 and obtain , which is equivalent to the original equation. If the perimeter of a rectangle is 54 cm and the length is 15 cm, what is the width? Either form is correct, but the improper fraction form will be more useful in checking your solution. Remember that when we multiply a whole number by a fraction, we use the rule. The multiplication rule allows us to avoid these operations when solving an equation involving fractions by finding an equivalent equation that contains only whole numbers. If the margin M was one-fifth of the cost C , find the cost of the article. Many students think that when they have found the solution to an equation, the problem is finished.

To eliminate the fraction in the equation we need to multiply by a number that is divisible by the denominator 3. If the margin M was one-fifth of the cost C , find the cost of the article. We should think in this manner:. Finding the values that make a conditional equation true is one of the main objectives of this text. Take the fraction 1 2 for example. A solution or root of an equation is the value of the variable or variables that make the equation a true statement. We have two fractions to eliminate. Here our thinking should proceed in this manner. Why do we add 3 to both sides? To solve for x we first write the proportion:. Using the division rule, we obtain To eliminate the fraction we need to multiply by a number that is divisible by the denominator. Example 9 What number x has the same ratio to 3 as 6 has to 9? However, in most cases, the solutions to these equations will not appear in simplified form the provided calculator computes the simplification automatically. Below is an example using this method. Dividing by 5 does not help find the solution however.
