At the beginning, the Ghana Empire practiced exclusively African polytheistic religions. However, Islamic scholars arrived midway through the empire's reign and resulted in the conversion of the leaders to Islam. For the latter half of the empire's time, it practiced Islam predominantly, but with syncretic African touches.
Ghana's Kings did not practice both religions at the same time. They first practiced local traditional religions and when Islam arrived in Ghana, they converted to Islam, but kept some distinctive touches from their traditional religions. They did not start as Muslims since Islam had not reached them yet. They converted to Islam because they were convinced it was correct. They kept small touches of their original religion out of loyalty to their history, culture, and those Ghanians who had not converted to Islam.
The most prominent religion practiced in Ghana is the traditional worship of Nyame. Some festivals that have stemmed from this religion that are popular today are the Ghana Voodoo festival and the Apoo festival.

Islam is the predominant historical religion of the West African interior and the far west coast of the continent; Christianity is the predominant religion in coastal regions of Nigeria, Ghana, and Cote d'Ivoire; and elements of indigenous religions are practiced throughout. Before the decline of the Mali and Songhai Empires there was a sizable group of Jewish communities in areas like Mali, Senegal, Mauritania, and Nigeria. Today there are small Jewish populations in Ghana, Nigeria and Mali. Along with historic migrations, these religions have culturally linked the peoples of West Africa more than those in other parts of Sub-Saharan Africa. --sorry; I couldn't find actual percentages--you might have to break down by country--
