Answer the question.Use two different methods to simplify the fraction. Explain each step of your work.
What will be an ideal response?
One method is to simplify the numerator and denominator separately, multiply the numerator by the reciprocal of the denominator, and simplify the resulting fraction, if possible.
= 
= 
? 
= 
The second method is to multiply the numerator and denominator of the complex fraction by the least common denominator of the fractions in the numerator and the fractions in the denominator of the complex fraction, and then simplify the resulting fraction, if possible.
= 
= 
=
