A perfect number is defined as one for which the sum of all the unique factors less the number itself is equal to the nu
A perfect number is defined as one for which the sum of all the unique factors less the number itself is equal to the number. For instance, 6 is a perfect number, because the factors of 6 (apart from 6 itself) are 1, 2 and 3, and 1+2+3=61+2+3=6. Which of the following is also a perfect number? A 12 ...

Assume the number of managers is X. The questions says that 3/7 of the managers are female and that there are 42 female managers. Translate this into an equation:
$$\frac{3}{7}$$ of X = 42
$$\frac{3}{7}$$ * X = 42
3X = 42*7
X = $$\frac{42\cdot7}{3}$$
X = 98
