Question

Joy organized a large wedding.

guests had to chose their meal from beaf, chicken or veg.
1/3 of the guests chose beaf.
5/12 of the guests chose chicken.
69 of the guests chose veg.
How many people were at the wedding?

Answer 1

276 guests

Explanation:

First, we need to combine the given fractions. Do this by finding a common denominator. 3 can go into 12 four times, but 12 cannot go into 3, therefore multiply 1/3 by 4 to get a common denominator.

1/3 x 4 = 4/12

Now add the two fractions together.

4/12 + 5/12 = 9/12 = 3/4

This means that the other 1/4 of guests chose the veg. option. If 69 people chose the veg. then we need to multiply that by four to find the total number of guests.

69 x 4 = 276

The wedding had 276 guests.
