Complex Rational expressions ( Help) ...Simplify?

Question

_1_
x+y
__________
_1_ + _1_
x ...........y

Answer 1

Remember that A divided by 1/B equals A times B.

First the denominator part:
(1/x) + (1/y) = (x+y)/(x y)

Therefore dividing by the denominator equals to multiplying by
(x y) / (x+y).

Hence the whole expression amounts to (x y) / (x+y)^2

Answer 2

1/(x+y) / (1/x+1/y) =
1/(x+y) / ( (x+y)/xy ) =
xy/(x+y)²

if you want to learn (and have a chance to get your diplomas), then do it yourself, next time. (and ask if your solution is correct instead of asking the solution)

Answer 3

actually iam not able to understand the question plz make it clear & mail it to [e-mail] so tht i can simplify

Answer 4

you should try asking someone at home as they can explain fully how to do it and then next time you will know how to do it

Answer 5

(1/(x + y)) / ((1/x) + (1/y))

Multiply the bottom by xy

(1/(x + y)) / ((x + y)/(xy))

(1/(x + y)) * ((xy)/(x + y))

(xy)/((x + y)(x + y))
(xy)/(x^2 + 2xy + y^2)

Answer 6

finndo is correct
