Answer:
From 2.5 y to 1.5 y there is a 40 % DECREASE in the value.
Step-by-step explanation:
Here, the initial value = 2.5 y
The final value of 1.5 y
Now,as Final Value < Initial Value
So, there is a DECREASE IN THE VALUE.
Now, decrease in the value = Initial value - Final Value
= 2.5 y = 1.5 y = 1 y
or, there is a decrease of ( 1 y) in the given value.
Now, Percentage decrease in the value is given as:

or, Percentage Decrease = 40%
Hence, from 2.5y to 1.5y there is a 40 % DECREASE in the value.
