Question

I'll fan & medal!!
Find the sum.

Answer 1

\[\frac{ 5 }{ xy } + \frac{ x ^{2} }{ y ^{2}}\]

Answer 2

you can only add fractions if they have the same bottom denominators, so need to do something , mulitply by the common denominator first...

Answer 3

the common denominator is xy^2

Answer 4

\[[\frac{ 5 }{ xy }+\frac{ x^2 }{ y^2 }]*\frac{ xy^3 }{ xy^3 }\]

Answer 5

5x^2 is the numerator?

Answer 6

The common denominator is the product of the two, then multiply by that over itself, the same as multiplying by 1...

Answer 7

i dont gt it

Answer 8

\[[\frac{ 5 }{ xy }+\frac{ x^2 }{ y^2 }]*\frac{ xy^3 }{ xy^3 } = \frac{ 5y^2 }{ xy^3 }+\frac{ x^3 y}{ xy^3 } =\]

Answer 9

now you can add them since they are both over xy^3
