To give more specific information (this may be helpful to anyone), the ratio are obtained as following:
For Cu2O to CuO conversion:
1) Divide the Cu2O wt-% by the molecular weight of Cu2O (143.09) and multiply it by 2 (2 atoms of Cu in one molecule of Cu2O). You obtain here the atomic proportion of Cu.
2) Multiply this result by the molecular weight of CuO (79.55)
If you calculate this, you obtain the ratio proposed by the other: (2 / 143.09) * 79.55 = 1.11188761
The other ratio is simply this inverse of 1.11188761
