Solution:

(b)

The amount of mineral fuels, including oil and vehicle is;


99.3+60.5=159.8

The total amount of exports is;


450.7

Thus, the percentage relative of mineral fuels, including oil and vehicle to total exports is;


(159.8)/(450.7)*100=35.5

(c) The total amount of top five Canadian exports is;


99.3+60.5+34.5+18.3+14.3=226.9

Thus, the percentage relative of mineral fuels, including oil and vehicle to top five exports is;


(159.8)/(226.9)*100=70.4
