    LCM=20x^2y^2

    \frac {5}{4x^2y}+\frac{3}{5xy^2}

    =\frac{25y+12x}{20x^2y^2}

    divide the LCM by the denominator of the first fraction and multiply it with the numerator.. Same with second one and as it is a "+" sign in between add a + sign..

    You get the answer

    It is same as you do with numbers....

    For example how will you do \frac{1}{5}+\frac 1{6} ?
