For easy calculation lets take the value as integer

1. $$\frac{1}{3}$$ of refugee housing expenditures = $$\frac{1}{3} * (12)$$= 4%

2. $$\frac{1}{5}$$ emergency workers expenditures = $$\frac{1}{5} * (20)$$= 4%

3. $$\frac{1}{4}$$ of its commodities expenditures = $$\frac{1}{4} * (20)$$ = 5%

4. $$\frac{2}{3}$$ of its post-disaster assistance expenditures = $$\frac{2}{3} * (12)$$= 8%

Therefore total expenditure = $$4 + 4 + 5 + 8 = 21$$% = i.e. $$(0.21 * 60)$$ million = 12.6 million nearly equals to 13 million
