remember
((a)/(b))/((c)/(d))=((a)/(b))((d)/(c))=(ad)/(bc)

try to combine fractions in numerator and denomenator

numerator:
(1)/(x)+(2)/(y)

make common denom

multiply left one by
(y)/(y) and right one by
(x^2)/(x^2)


(y)/(yx^2)+(2x^2)/(yx^2)=(2x^2+y)/(yx^2)

denomenator


(5)/(x)-(6)/(y^2)

make common denom

multiply left one by
(y^2)/(y^2) and right one by
(x)/(x)


(5y^2)/(xy^2)-(6x)/(xy^2)=(5y^2-6x)/(xy^2)


combining we get


((1)/(x^2)+(2)/(y))/((5)/(x)-(6)/(y^2))=


((2x^2+y)/(yx^2))/((-6x+5y^2)/(xy^2))=


((2x^2+y)/(yx^2))((xy^2)/(-6x+5y^2))=


(2x^3y^2+xy^3)/(-6x^3y+5x^2y^3)=


((2x^2y+y^2)/(-6x^2+5xy))((xy)/(xy))=


((2x^2y+y^2)/(-6x^2+5xy))(1)=


(2x^2y+y^2)/(-6x^2+5xy)

Answer:

The simplified version of the given expression is
((2x^2y+y^2)/(5xy-6x^2) )

Explanation:

We are given an expression which is a complex fraction:


((1)/(x^2) +(2)/(y) )/((5)/(x) +(6)/(y^2) )

We can take LCM of these fractions to get:


((y+2x^2)/(x^2y) )/((5y^2-6x)/(xy^2) )

Taking the reciprocal of the lower fraction to change it to multiplication:


(y+2x^2)/(x^2y) ×
(xy^2)/(5y^2-6x)


(2x^2y+xy^3)/(5x^2y^3-6x^3y)

Taking xy as common from both the numerator and the denominator to get:


(xy)/(xy) ((2x^2y+y^2)/(5xy-6x^2) )


((2x^2y+y^2)/(5xy-6x^2) )
