In a survey of 200 employees, 65% agreed that the management of the cafeteria should be changed.

In case you want to find the number of employees who agreed to change the administration of the cafeteria, we make a rule of three:

200 ---------------> 100%

x -------------------> 65%

Where the variable "x" represents the number of employees who agreed to change the administration of the cafeteria.

That means that of the 200 employees, 130 agreed to change the administration of the cafeteria.

130 employees agreed to change the administration of the cafeteria.

the first one, all those points on the line just make a strait line.
