Answers

Answer:

40%

Step-by-step explanation:

Finley's pumpkin had a mass of 6.5 kg before he carved it.

After carving it, the pumpkin had a mass of 3.9 kg.

Now, we are asked to determine the % decrease in the mass of the pumpkin.

Therefore, the % decrease in mass is given by

$\frac{\textrm {Initial Mass - Final Mass}}{\textrm {Initial Mass}} * 100= (6.5 - 3.9)/(6.5) * 100 = 40$ %. (Answer)
