6.5 kg to 3.9 kg, what was the percent decrease
igomit [66]

Answer: 40%

Step-by-step explanation:

Given,

Initial mass = 6.5kg

final mass = 3.9kg

So, Change in mass = initial mass - final mass

                                  = 6.5 - 3.9

                                  = 2.6 kg

and,

Change in percentage of mass = \frac{change in mass}{original mass} * 100

Change in percentage of mass = \frac{2.6}{6.5} * 100

                                                    = 40
