In other words, the an adverse symbol can stay in the numerator. And also so, after ~ inverting the 2 numbers, the an unfavorable symbol is now attached to 2. This is also a valid answer together the reciprocal of the initial fraction.
Thereis one more means to compose the mutual of this an unfavorable fraction. The an adverse symbol may not be attached either come the molecule or denominator.
It is also correct to place the an unfavorable symbol straight to the left the the fraction bar. This is exactly how it looks!
So in summary, if the fraction is negativeits reciprocal have the right to be written three ways.Negative symbol continues to be with the numeratorNegative symbol stays with the denominatorNegative symbol remains with the spring bar
Example 3: write the reciprocal of the negative portion below in three various ways.
