The fraction of the cost of the torch and the total price is
.
Explanation:
Given,
The cost of torch and a battery = 2.50
The torch costs 1.50 more than the battery.
To find the fraction of the cost of the torch and the total price.
Let,
The cost of a battery = x
The cost of the torch = x+1.50
According to the problem,
x+1.50+x = 2.50
or, 2x = 1
or, x = 0.50
Hence,
The cost of a battery =0.50
The cost of the torch = 0.50+1.50 = 2.00
The fraction of the cost of the torch and the total price =
=
