The following part of the problem statement should be deleted, since it makes no contribution to defining the problem:
"a. The ratio of males to total attendance is nothing. (Simplify your answer.) b. The ratio of females to total attendance is nothing. (Simplify your answer.) c. The ratio of males to females is nothing. (Simplify your answer.) d. The ratio of females to males is nothing. (Simplify your answer.)"
But I will give you answers anyway.
(a)
72 / (72 + 105) ≅ 0.41
(b)
105 / (72 + 105) ≅ 0.59
(c)
72/105 ≅ 0.69
(d)
105/72 ≅ 1.46
