ab + b^2/4ab^5
______________
a+b/6a^2b^4
Answer by RAY100(1637) (Show Source): You can put this solution on YOUR website!
{ (ab+b^2) / (4ab^5)} / {(a+b)/(6a^2b^4)}
.
invert and multiply
.
{ (ab+b^2)/(4ab^5)} * {(6a^2b^4)/(a+b)}
.
factor and simplify by cancelling like terms
.
{ (b)(a+b) / (4 a b^5)} * { (6 a^2 b^4)/ (a+b) }
.
{ 3 a /2 }
.
(3/2) a = 1.5a
.
check,,,Let a = 2,,,,b=1,,,,both original and answer = 3,,,,ok
