Penyelesaian

Gunakan maklumat itu untuk cari jumlah 100%.
Gunakan formula berikut:-

Decrease in 2011 —————————— 300,000 tourist

100% —————————— Total number of tourists in 2011

Percentage of decrease = ( number of decrease /total number of tourists in 2011 ) X 100

300,000 X 100

3,750,000

= 8%

Answer = The percentage of the decrease in 2011 is 8%
