rita ran for president of the chess club, she recieved 12 votes. there were 60 members in the club. what percentage of the club members voted for rita?

20% of the club members voted for Rita

Step-by-step explanation:

Percentage problems can be explained as a rule of three problem

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too. In this case, the rule of three is a cross multiplication.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease. In this case, the rule of three is a line multiplication.

In this problem, the measures are:

- The number of people that voted for Rita

- The total number of people

As the number of people that voted for Rita increases, the total number of people will increase too. So, the relationship between the measures is direct.

If we want to know the percentage of the club members voted for rita, we want to know how many club members voted for Rita among 100 members. So

12 voted for Rita - 60 people

x voted for Rita - 100 people

60x = 1200

x = 20%

20% of the club members voted for Rita
