#70%#

24 is 30% of 80

#(24/80=3/10=30%)#

Change = 100% -30% = 70%

#70%#

The percent decrease or increase can be calculated from:

#("amount of the change")/("original amount") xx 100%#

In this case the change was from #80 rarr 24#

#80-24 = 56" "# It was a decrease of 56.

#56/80 xx 100%#

=#70%#
