For this problem, the deltaG obtained after adding reactions 2 and 3 was negative. However, when we divided it by the deltaG of reaction 1, it was written as a positive number. Why is there no negative sign? Is it because if the deltaG was negative, we would end up getting a negative number of moles?

You get a -dG from the two reactions, and this energy is used to drive the ATP production. It's a transfer of energy between two separate entities, so the heat given off by the two reactions is used to make ATP. Like hot water mixing with cold water, the hot water gives off energy and the cold water gains energy.
