Asher is 40 years older than his cousin. 4 years from now, his cousin will be ¹₃ of his age while his nephew will be ²₅ of his cousin. Express his nephew’s present age as a fraction of Asher's present age. Leave your answer in its simplest form.

	Asher	Asher's cousin	Asher's nephew	Difference between Asher and Asher's cousin
Before	15 u - 4	5 u - 4	2 u - 4	40
Change	+ 4	+ 4	+ 4
After	3x5	1x5
		5x1	2x1
Comparing Asher, his cousin and his nephew in the end	15 u	5 u	2 u	10 u

The repeated identity is the age of Asher's cousin. LCM of 1 and 5 is 5.

The difference in age between Asher and Asher's cousin remains unchanged.

Difference in age between Asher and Asher's cousin
= 15 u - 5 u 
= 10 u 

10 u = 40

1 u = 40 ÷ 10 = 4

His nephew's present age 
= 2 u - 4
= 2 x 4 - 4
= 8 - 4
= 4

Asher's present age
= 15 u - 4
= 15 x 4 - 4
= 60 - 4
= 56

His nephew's present age as a fraction of Asher's present age
= ⁴₅₆
= ¹₁₄

Answer(s): ¹₁₄
