Question

6.5 kg to 3.9 kg, what was the percent decrease

Answer 1

Answer: 40%

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 =
`(change in mass)/(original mass) * 100`

Change in percentage of mass =
`(2.6)/(6.5) * 100`

= 40
