A triangle has three sides. A ratio is a comparison of two things. We pick two different sides of the triangle to compare (because there is not much point in comparing one thing to itself). How many ways are there to do this? The first choice has 3 options, and the second has 2, so we have a total of 
possibilities.
Answer:
The complete question is as shown in the attached figure 1
The Venn diagram is the attached figure 2
Let: R⇒ribs , H⇒hamburgers and C⇒corn
People would eat all three = 53
People would eat only R and H = 56 - 53 = 3
People would eat only C and H = 54 - 53 = 1
People would eat only R and C = 55 - 53 = 2
People would eat only H = 60 - (53+3+1) = 60 - 57 = 3
People would eat only R = 59 - (53+3+2) = 59 - 58 = 1
People would eat only C = 56 - (53+1+2) = 0
See Vinn diagram.
=========================================================
a. How many people did not want any of these foods?
people did not want any of these foods = 64 - (53+3+1+2+3+1) = 1
b. How many people would eat ribs but not corn?
people would eat ribs but not corn = 1+3 = 4
c. How many people would eat something as long as it was not a hamburger?
people would eat something as long as it was not a hamburger= 1+2 = 3
d. How many people would eat only corn?
people would eat only corn = 0
e. How many people would eat exactly two foods?
people would eat exactly two foods = 1 + 2 + 1
