Should the question read: "In math, a over 5 equals b over 7 equals 8 over 3. Does a plus b equal 31.99?"Do you mean a/5 = b/7 = 8/3?If so, we can look at a and b separately.a/5 = 8/3a = 5*(8/3)a = 40/3a = 13.33b/5 = 8/3b = 7*(8/3)b = 56/3b = 18.67It looks as though you have added a and b together to get 13.33 + 18.67 = 32 (if you did b=18.66 then you would get 31.99 but it should be 32).
