How Do You Add Subtract Multiply And Divide Rational Numbers

To add or subtract two rational expressions with the same denominator, we simply add or subtract the numerators and write the result over the common denominator. When the denominators are not the same, we must manipulate them so that they become the same. In other words, we must find a common denominator. To divide two numerical fractions, we multiply the dividend (the first fraction) by the reciprocal of the divisor (the second fraction). For example: = 2 9 ÷ 8 3 = 2 9 ⋅ 3 8 Multiply by the reciprocal = 2 3 ⋅ 3 ⋅ 3 2 ⋅ 4 Factor numerators & denominators = 2 3 ⋅ 3 ⋅ 3 2 ⋅ 4 Cancel common factors = 1 12 Multiply across

How Do You Add Subtract Multiply And Divide Rational NumbersExample 1: 3 x 2 2 ⋅ 2 9 x We can multiply rational expressions in much the same way as we multiply numerical fractions. = 3 x 2 2 ⋅ 2 9 x = 3 ⋅ x ⋅ x 2 ⋅ 2 3 ⋅ 3 ⋅ x Factor numerators and denominators ( Note x ≠ 0) = 3 ⋅ x ⋅ x 2 ⋅ 2 3 ⋅ 3 ⋅ x Cancel common factors = x 3 Multiply across Recall that the original expression is defined for x ≠ 0 . How to Add Subtract Multiply and Divide When the rational number is something simple like 3 or 0 001 then just use mental arithmetic or a calculator But what about when it is in p q form Here we will see those operations in a more general Algebra style You might also like to read Fractions in Algebra

Dividing Rational Expressions. To divide two fractions, we multiply by the reciprocal of the divisor, as illustrated: 5 8 ÷ 1 2 = 5 8 ⋅ 2 1 = 5 ⋅ 1 2 8 4 ⋅ 1 = 5 4. Dividing rational expressions is performed in a similar manner. For example, x y2 ÷ 1 y = x y2 ⋅ y 1 = x ⋅ 1 y y2 y ⋅ 1 = x y.
