Answer 1

Half of 3600 had ordered meals..which is equal to 1800.
Now, every one of twelve has special dietary needs:
12 = 1
1800= ?
=1800/12
=150
Therefore..150 people have special dietary needs.

Answer 2

Answer:

150 people have special dietary needs.

Step-by-step explanation:

Given : A conference with 3600 participants gathers in Albany. One of every twelve people attending the conference who have ordered meals has special dietary needs. Half of those attending the conference signed up for meals.

To find : How many have special dietary needs?

Solution :

A conference with 3600 participants gathers in Albany.

Half of those attending the conference signed up for meals.

i.e. number of participants attending is $\frac{3600}{2}=1800$

One of every twelve people attending the conference who have ordered meals has special dietary needs.

i.e. for 12 participants we have 1 special dietary needs.

For 1 participants we have $\frac{1}{12}$ special dietary needs

For 1800 participants we have $\frac{1800}{12}$ special dietary needs

For 1800 participants we have 150 special dietary needs

Therefore, 150 people have special dietary needs.
