Find the percent of increase or decrease? 2.5y to 1.5y

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.
