The solution of equations is the central theme of algebra.

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.

Now we must eliminate 2x on the right side by subtracting 2x from both sides. Note that in the example just using the addition rule does not solve the problem. Apply the orderly steps established in this section to systematically solve equations. We should think in this manner:. The reciprocal of the fraction 3 4 would therefore be 4 3. Help Tutorial. Example 5 Solution See if you obtain the same solution by multiplying each side of the original equation by We now have an equivalent equation that contains only whole numbers. Keep in mind that we wish to obtain x alone on one side of the equation. If there are 24 men in the class, how many women are in the class? 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.

Note that there are four terms in this equation. Below are multiple fraction calculators capable of addition, subtraction, multiplication, division, simplification, and conversion between fractions and decimals. Ability to solve an equation mentally will depend on the ability to manipulate the numbers of arithmetic. We will also introduce ratio and proportion and use the multiplication rule to solve proportions. 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. Simply, the numerators and denominators of each fraction are multiplied, and the result forms a new numerator and denominator. If possible, the solution should be simplified. Solve simple equations mentally. Fifth Check your answer. Note that in each case only the numerator of the fraction is multiplied by the whole number. The ratio of a number x to a number y can be written as x:y or.
