$${numbers}\:{of}\:{disc}=\frac{\mathrm{11}×\mathrm{2}}{\frac{\mathrm{22}}{\mathrm{7}}×\frac{\mathrm{0}.\mathrm{5}}{\mathrm{2}}×\frac{\mathrm{0}.\mathrm{5}}{\mathrm{2}}} \\ $$$$=\frac{\mathrm{11}×\mathrm{2}×\mathrm{4}×\mathrm{7}}{\mathrm{22}×\mathrm{0}.\mathrm{5}×\mathrm{0}.\mathrm{5}}=\frac{\mathrm{28}×\mathrm{100}}{\mathrm{5}×\mathrm{5}}=\mathrm{112} \\ $$
