First. In the numerator, factor out an x. In the denominator, factor out a 4. this will leave a common factor that can be divided out.
Second.change the numerator to 8ab. Check that to see if it is right.
change the denominator to 4b^2
now you have 8ab/4b^2 reduce the 8/4, and the b/ b^2
1) ánswer X/8
