Finley’s pumpkin had a mass of 6.5 kilograms before he carved it. after carving it the pumpkin had a mass of 3.9 kilograms. what was the percent decrease?

Hello.

The percent decrease in the mass of the pumpkin for this case will be given by:
 (100 - (3.9 / 6.5) * 100) =
 (100-60) =40%

 After carving it, the pumpkin decreases a percent of 40% in the mass.

Have a nice day
