1)
$2: \frac{3}{5}+ \frac{3}{5}:2+1 \frac{1}{2} :6+6:1 \frac{1}{2} =2* \frac{5}{3}+ \frac{3}{5}* \frac{1}{2} + \frac{3}{2} * \frac{1}{6} +6: \frac{3}{2}=$ $=\frac{10}{3}+ \frac{3}{10}+ \frac{1}{4} +6* \frac{2}{3}= 3 \frac{1}{3} + \frac{3}{10}+ \frac{1}{4} +4=7 \frac{1}{3} + \frac{12}{40}+ \frac{10}{40} =$ $=7 \frac{1}{3} + \frac{22}{40} =7 \frac{1}{3} + \frac{11}{20} =7 \frac{20}{60} + \frac{33}{60}=7 \frac{53}{60}$

2)
$6 \frac{1}{4} *8-3 \frac{2}{3} *5 \frac{1}{2} +2 \frac{2}{5}*4 \frac{7}{12}= \frac{25}{4} *8- \frac{11}{3} * \frac{11}{2} +\frac{12}{5}* \frac{55}{12}= 50- \frac{121}{6}+11=$ $=61-20 \frac{1}{6}=40 \frac{5}{6}$

3)
$2 \frac{1}{2} *48-3 \frac{2}{3} : \frac{1}{18}+5 \frac{5}{12}: \frac{7}{36} = \frac{5}{2} *48- \frac{11}{3} : \frac{1}{18}+ \frac{65}{12}* \frac{36}{7}=$ $=120- \frac{11}{3} * 18}+ \frac{65}{1}* \frac{3}{7}=120-66+ \frac{195}{7}=54+27 \frac{6}{7} =81 \frac{6}{7}$

4)
$13 \frac{1}{2} :1 \frac{1}{3} +16 \frac{1}{2} *1 \frac{5}{11} +19 \frac{1}{4} : \frac{4}{25} = \frac{27}{2} :\frac{4}{3} + \frac{33}{2} *\frac{16}{11} + \frac{77}{4} : \frac{4}{25} =$ $=\frac{27}{2}*\frac{3}{4} + \frac{33}{2} *\frac{16}{11} + \frac{77}{4} * \frac{25}{4} = \frac{81}{8} +24+ \frac{1925}{16} =10 \frac{1}{8} +24+120 \frac{5}{16}=$ $=10 \frac{2}{16} +24+120 \frac{5}{16}=154 \frac{7}{16}$
