Final answer:
To calculate the total number of employees, given the ratio of union to non-union members is 2:3 and there are 45 non-union members, we find out that there are 30 union members. Adding these together gives a total of 75 employees.
Step-by-step explanation:
The student asked about the total number of employees at a company, given the ratio of union members to non-union members is 2 to 3 and there are 45 nonunion members. To find the total number of employees, we can use the given ratio. For every 2 union members, there are 3 non-union members. If we have 45 non-union members, this means we have 45 divided by 3 parts, which equals 15. Each 'part' here represents a set of union members, so we have 15 sets of 2 union members each, yielding 30 union members. Adding this to the number of non-union members (45), we get a total of 75 employees at the company.
