Answer:
276 guests
Step-by-step explanation:
So 1/3 is equal to 4/12.
4/12+5/12 is equal to 9/12
Therefore the 3/12 of guests chose vegetarian.
3/12 is equal to 69.
That means 1/12 is 23 because 69/3 is 23.
Then the total number of guests is 12/12 and since 1/12 is 23 that means 12/12 is 276. (23*12)
