Answer 2

Answer:

Let us take the number to find to be x

If that's the case, it has reduced 40% of itself

Thus the equation will be as follows

x - 40x/100 = 135

x - 2x/5 = 135 ( 40/100 is simplified as 2/5)

5x-2x/5 =135

3x= 5(135)

3x= 675

x= 675/3

x=225

Thus, the value of the number that is decreased by 40% is 225
