I am trying to do this problem and this is what I have got so far
Divide
-49+7w/11 / 9w-63/121
(-49+7w)(121)/9w-63)(11)
(w+7)(w-7)(121)
(w+9)(w-7)(11)
can you help from here
Certainly! It looks like you've made some progress already. Let's continue from where you left off.
You correctly factored the numerator: (-49+7w) = (w-7)(-7) = -7(w-7).
Now let's factor the denominator: (9w-63) = 9(w-7) = 9(w-7)(1).
So the expression can be simplified as follows:
(-49+7w/11) / (9w-63/121)
= -7(w-7)/(11*9(w-7)) / (121/1)
= -7(w-7)/99(w-7) / 121
= (-7/99)/(121/1)
To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping its numerator and denominator. So,
= (-7/99) * (1/121)
= -7/(99*121)
At this point, we have simplified the expression as much as possible. The final answer is -7/(99*121).
I hope this helps! Let me know if you have any further questions.
