Finley’s pumpkin had a mass of 6.5 kilograms (kg) before he carved it. After carving it, the pumpkin had a mass of 3.9 kg. What was the percent decrease in the mass of the pumpkin?

Answer: 40% decrease.Step-by-step explanation: To find the percent decrease we will be using the "Percent Decrease" equation.change = percent change x actualTo find the change subtract 3.9 from 6.5, which is 2.6 kg, or 2.6 as the change.2.6 = percent change x actualThe actual is 6.5, because the actual or original mass of the pumpkin was 6.5 kg.2.6 = percent change x 6.5       (Solve for p, percent change.)2.6 = p x 6.52.6/6.5 = p0.4 = pNow, to find the percent decrease multiply the decimal 0.4 by 100.0.4 x 100 = 40, or 40%.
