numbers of disc=((11×2)/(((22)/7)×((0.5)/2)×((0.5)/2)))  =((11×2×4×7)/(22×0.5×0.5))=((28×100)/(5×5))=112
$${numbers}\:{of}\:{disc}=\frac{\mathrm{11}×\mathrm{2}}{\frac{\mathrm{22}}{\mathrm{7}}×\frac{\mathrm{0}.\mathrm{5}}{\mathrm{2}}×\frac{\mathrm{0}.\mathrm{5}}{\mathrm{2}}} \\ $$$$=\frac{\mathrm{11}×\mathrm{2}×\mathrm{4}×\mathrm{7}}{\mathrm{22}×\mathrm{0}.\mathrm{5}×\mathrm{0}.\mathrm{5}}=\frac{\mathrm{28}×\mathrm{100}}{\mathrm{5}×\mathrm{5}}=\mathrm{112} \\ $$
