The percentage change #=color(green)(66.67%#

The initial value # = 63#

The final value # = 105#

The change # = color(blue)(42#

The percentage change #= # (change in value) / (initial value) #xx 100#

#=color(blue)(42) / 63 xx 100#

#=color(green)(66.67%# (rounded off to nearest hundredth)

Percentage change is #66 2/3%#

The change from #63# to #105# is given by #105-63=42# (i.e. the latter figure minus earlier figure).

For percentage change, we should divide the change by earlier figure and then multiply by #100#.

Hence percentage change is #42/63xx100# (dviding by #21#)

= #(2cancel42)/(3cancel63)xx100#

= #200/3=66 2/3%#
