Draw a dividend rectangle 10cm long to show the percentage of minerals mined in country A. 

Answer 1

Drawing a divided rectangle.
Limestone 10  x 10 = 1 cm
                  100
Coal 20    x 10 = 2 cm
       100
Iron ore 50   x 10 = 5 cm
            100
Trona 20  x 10 = 2 cm
         100

Limestone	IRON ORE	coal	Trona
5cm	2cm	2cm	1cm
