Denver gets 5/19 of the dog food.

natka813 [3]

Answer:

Fido have $\frac{42}{95}$ of the dog food (44.211 %), Engle have $\frac{28}{95}$ of the dog food (29.474 %) and Denver have $\frac{5}{19}$ of the dog food (26.316 %).

Step-by-step explanation:

If Denver gets $\frac{5}{19}$ of the dog food, then Engle and Fido share $\frac{14}{19}$ of the dog food. If Fido have $x$ of the dog food, then Engle have $\frac{4}{3}\cdot x$ such that:

$x + \frac{4}{3}\cdot x = \frac{14}{19}$

$\frac{5}{3}\cdot x = \frac{14}{19}$

$x = \frac{42}{95}$

Fido have $\frac{42}{95}$ of the dog food (44.211 %), Engle have $\frac{28}{95}$ of the dog food (29.474 %) and Denver have $\frac{5}{19}$ of the dog food (26.316 %).

The 80th percentile = 0.84
