Answer
Maria is personally responsible for $\frac{1}{4}$ of the ABC's accounts
Work Step by Step
Maria’s department has $\frac{3}{4}$of all of the accounts within
the ABC Advertising Agency, and Maria is personally responsible for $\frac{1}{3}$ of them.
So, Maria is personally responsible for $\frac{1}{3}$ of the $\frac{3}{4}$ of the accounts that her department has within the ABC.
To find the portion of all of the accounts at ABC that Maria is personally responsible for, we multiply $\frac{1}{3}$ by $\frac{3}{4}$
$\frac{1}{3}$ $\times$ $\frac{3}{4}$ =
$\frac{3}{12}$ =
$\frac{1}{4}$
Maria is personally responsible for $\frac{1}{4}$ of ABC's accounts
