(a) increase from 10 to 11percentage increase = increase/ original x 100
=(11-10)/10 x 100
=1/10 x 100
=10%
(b) decrease from 16 to 10
percentage decrease = decrease/ original x 100
=(16-10)/16 x 100
=6/16 x 100
=37.5%
(c) increase from 8 to 22
percentage increase = increase/ original x 100
=(22-8)/8 x 100
=14/8 x100
=175%
