Help me calculate the percentage of mix HNO3 and H3PO4?

3.85g of 70% HNO3 mix with 46.15g of 85% H3PO4.Please help to calculate the concentration of HNO3 and H3PO4 in %.Help me calculate the percentage of mix HNO3 and H3PO4?
HNO3: (3.85 g) (0.70) / (3.85 g + 46.15 g) = 0.0539, or 5.39%.

H3PO4: (46.15) (0.85) / (3.85 g + 46.15 g) = 0.7846, or 78.46%.
