A disc has a diameter of 21 cm while a mini disc has a diameter of 14cm. Write the ratio of the mini disc diameter to the disc diameter.
Answer: Let the diameter of the mini disc be 
while the diameter of the disc be 
. To get the ratio of the mini disc diameter to the disc diameter, we just simply have to divide the diameter of the mini disc by the diameter of the disc and then represent the fraction in ratio form. The ratio of the disc diameters is given by:
Ratio of the mini disc diameter to the disc diameter = Diameter of mini disc / diameter of disc
Ratio of the mini disc diameter to the disc diameter = 
Ratio of the mini disc diameter to the disc diameter = 2 : 3
