Polynomial (algebra) Is my work correct?

desiree-h

(4/7y^2-1/5y^2+7/9) + (1/3y^2-1/3y+2/5) This problem is suppose to be in vertical form.

When I get common denominators, combine like terms, and add like terms in a column....

My answer: 19/21y^2-8/15y+53/45

I feel as if I'm doing something wrong.
