$\frac{4E-5}{20}+5$

Step-by-step explanation:

We have been given that Eli is E years old.

Devin is 1 1/4 younger than Eli, therefore, Devin's age in terms of E will be:

$\text{Devin's age in terms of E}=E-1\frac{1}{4}$

$\text{Devin's age in terms of E}=E-\frac{5}{4}$

Further we are told that April is 1/5 as old as Devin. So April's age will be,

$\text{April's age in terms of E}=\frac{E-\frac{5}{4}}{5}$

Upon simplifying our expression we will get,

$\text{April's age in terms of E}=\frac{(\frac{4E-5}{4})}{5}$

$\text{April's age in terms of E}=\frac{4E-5}{20}$

Now let us write Jill's age in terms of E.

We are told that Jill is 5 years older than April. So Jill's age will be,

$\text{Jill's age in terms of E}=\frac{4E-5}{20}+5$

Therefore, Jill's age in terms of E will be $\frac{4E-5}{20}+5$ .
