The yearbook club had a meeting. The meeting had 30 people, which is three-fifths of the club. How many people are in the club?
If 30 people represent three-fifths of the yearbook club, you can determine the total number of people in the club by setting up a proportion where 3/5 of the club equals 30 members.
Let's call the total number of people in the club X. Then we know that:
(3/5) * X = 30
To find X, you would divide both sides of the equation by 3/5:
X = 30 / (3/5)
To divide by a fraction, you multiply by its reciprocal. The reciprocal of 3/5 is 5/3, so:
X = 30 * (5/3)
Now, multiply 30 by 5 and then divide by 3:
X = (30 * 5) / 3
X = 150 / 3
X = 50
So, there are 50 people in the yearbook club.
