I don't know where you get your weights or why you want to use them.
The only problem that I see with your formula, assuming you like the weights, is that you have assigned a label that does not parse properly in English.
The fraction that you compute should be called something like, "Percent of households that have (one or more) children."
If you want to say something about "individual members" rather than households, ... Are you referring to only children as "members"? So, do you want to compute what your label says, "% children in households with two parents" -- as a contrast to 0 or 1 parent?
If so -- Your numerator will be a (weighted?) count of children, and the denominator denominator will be a (weighed?) count of households that do have one or more child. In your example, that sum would omit household 4.
