you have to get common denomicators
OpenStudy (anonymous):
so 21/18x is the answer?
OpenStudy (anonymous):
is it (7/6)x or 7/(6x)?
OpenStudy (anonymous):
its 7 over 6x
OpenStudy (anonymous):
right so the lcd is then 6x

OpenStudy (anonymous):
(7+2x)/(6x)
OpenStudy (anonymous):
so what would be the answer
OpenStudy (anonymous):
theres no 2 in the equation
OpenStudy (anonymous):
right, but you need common denominators
OpenStudy (anonymous):
if you want to add these fractions

ok u have
7/(6x) + 1/3
to add these fractions u need the same denominator
the lcm here is 6x so to get 6x for both u need to multiply the 1st fraction by 1 and the 2nd fraction by 2x/2x:
7/(6x)(1/1)+(1/3)(2x/2x)
7/(6x)+2x/(6x)
so it becomes
(7+2x)/(6x)
OpenStudy (anonymous):
and thats the end?
OpenStudy (anonymous):
yup
OpenStudy (anonymous):
that is the end , no way to simplify furter
OpenStudy (anonymous):
thats what i though biut wasnt sure. know anything about complex fractions?

what your question?
OpenStudy (anonymous):
1/b divided by 1/a-1/b
OpenStudy (anonymous):
i get confused when theres a fraction under under the divide sign
OpenStudy (anonymous):
To divide by a fraction, turn it upside down (reciprocal) and multiply by it instead.
