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

Respuesta :

Its mass decreased 40%

6.5 - 3.9 = 2.6

2.6 / 6.5 = 0.4

0.4 = 40%

Percent decrease = (decrease in weight / original weight) * 100

= [ (6.5 - 3.9) / 6.5] * 100

= (2.6 / 6.5) * 100

=  0.4 * 100

= 40 %   answer)
