Question 254609: I know the answer to the problem, I just need it explained. The book I'm using is a refresher, and it doesn't explain or give a similar example to this problem at all. It's a ridiculous problem of fractions divided by fractions, so basically fractions of fractions with a variable in for good measure. I hope I can make sense of it here:

The answer is apparently -%2818%2F11%29+%28%285x%2B1%29%2F%283x%2B1%29%29
I figured the -18/11 easy, but what happened to the variable fractions is far beyond me. Sorry for all the parenthesis... it was the only way I could get the problem to look anything like my workbook. Any takers?

Multiply thru by 99 to reduce the complexity:
= +%28%2827%29x+%2B+%2863%29x+%2B+%2818%29%29%2F%28%2844%29x+-+%2877%29x+-+%2811%29%29+
= +%2890x+%2B+18%29%2F%28-33x+-+11%29+
= 18*(5x + 1)/(11*(-3x - 1))
= your answer
The answer is apparently -%2818%2F11%29+%28%285x%2B1%29%2F%283x%2B1%29%29
