A fraction is a part of a whole.
The total number of guests at the wedding is 276.
<h3>What is a fraction?</h3>
A fraction is a part of a whole. It is expressed as a quotient, in which the numerator is divided by the denominator.
We have,
1/3 of the guests = beef
5/12 of the guests = chicken
69 of the guests = vegetarians
The fraction that chooses vegetarian is:
= 1 - 1/3 - 5/12
= (12 - 4 - 5) / 12
= 3/12
= 1/4
Now,
1/4 guest = 69
So,
The total number of guests at the wedding as a fraction can be considered as 1.
1/4 = 69
1 = 4 x 69
1 = 276
Thus the total number of guests at the wedding is 276.
