Question

Devin is 1 1/4 younger than eli. April is 1/5 as old as devin. Jill is 5 years older than April. If Eli is E years old what is Jill's age in terms of E?

Answer 1

`(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(1)/(4)`

`\text{Devin's age in terms of E}=E-(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}=(E-(5)/(4))/(5)`

Upon simplifying our expression we will get,

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

`\text{April's age in terms of E}=(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}=(4E-5)/(20)+5`

Therefore, Jill's age in terms of E will be
`(4E-5)/(20)+5`.
