(15)$\frac{9}{4}÷[\frac{1}{2}×(\frac{5}{6}-\frac{1}{3})]$

答案：
(1)原式$=\frac{1}{25}+\frac{27}{50}=\frac{29}{50}$
(2)原式$=\frac{13}{8}-\frac{2}{5}-\frac{3}{5}=\frac{13}{8}-1=\frac{5}{8}$
(3)原式$=12+\frac{3}{4}-\frac{1}{4}=12\frac{1}{2}$
(4)原式$=14.4+35=49.4$
(5)原式$=50-22.4=27.6$
(6)原式$=(17.82-8.1)÷3.6=9.72÷3.6=2.7$
(7)原式$=\frac{2}{3}+\frac{2}{3}=\frac{4}{3}$
(8)原式$=9.05-6.78-1.22=9.05-8=1.05$
(9)原式$=9.6÷(0.08×0.4)=9.6÷0.032=300$
(10)原式$=6+\frac{16}{27}+\frac{11}{27}=6+1=7$
(11)原式$=\frac{3}{5}×(153-53)=\frac{3}{5}×100=60$
(12)原式$=3+\frac{21}{5}+\frac{4}{5}=3+5=8$
(13)原式$=9+\frac{1}{9}=9\frac{1}{9}$
(14)原式$=3-\frac{3}{8}-\frac{5}{8}=3-1=2$
(15)原式$=\frac{9}{4}÷(\frac{1}{2}×\frac{1}{2})=\frac{9}{4}÷\frac{1}{4}=9$
