Finley's pumpkin had a mass of 6.56.56, point, 5 kilograms (\text{kg})(kg)left parenthesis, start text, k, g, end text, right parenthesis before he carved it. after carving it, the pumpkin had a mass of 3.9\,\text{kg}3.9kg3, point, 9, start text, k, g, end text.
what was the percent decrease in the mass of the pumpkin?

There was 40% decrease in the mass of the pumpkin.

Step-by-step explanation:

Given:

Mass of pumpkin before carving = 6.5 kg

Mass of pumpkin after carving = 3.9 kg

Decrease in mass = Mass of pumpkin before carving - Mass of pumpkin after carving = 6.5 kg - 3.9 kg = 2.6 kg

Now to find the percentage decrease in mass we need to divide Decrease in mass with the total mass of pumpkin before carving and then multiply by 100

% Decrease in mass =

Hence, there was 40% decrease in the mass of the pumpkin.
