Lorene,
1. Your question is unanswerable, because the answer will be different for every house.
2. The calculation you request would be very difficult -- perhaps impossible -- and would vary with the weather conditions.
3. Fortunately, performing the calculation (even if possible) is not particularly useful. If you want to reduce the rate of heat flow through your home's floor, walls, and ceiling, make your envelope as airtight as possible, and install insulation with a high R-value.
4. R-value is based on a test that measures all three types of heat flow (conduction, convection, and radiation), so you don't have to worry about percentages. For more information, see Understanding R-Value.
