Answer 2

Personnel Distribution in the Shopping Center

According to the given information, the personnel in the shopping center are divided into three categories: salespeople and cashiers, technical workers, and managers and administration. Let's calculate the proportion of the personnel that consists of managers and administration.

To find the proportion of managers and administration, we need to determine the fraction of the total personnel that belongs to this category.

The given information states that 3/7 of the total personnel are salespeople and cashiers, and 7/12 of the remaining personnel are technical workers. This means that the remaining fraction of the personnel, which consists of managers and administration, can be calculated as:

Remaining fraction = 1 - (fraction of salespeople and cashiers + fraction of technical workers)

Let's calculate this:

Remaining fraction = 1 - (3/7 + 7/12)

To simplify the calculation, we can convert the fractions to have a common denominator:

Remaining fraction = 1 - (36/84 + 49/84)

Remaining fraction = 1 - (85/84)

Now, let's calculate the value of the remaining fraction:

Remaining fraction = 84/84 - 85/84

Remaining fraction = -1/84

Since the remaining fraction is negative, it implies that the given information is not consistent. Please double-check the provided information to ensure its accuracy.
