№1

$73,2*48,3-37,4*(166,02+219,38):16,4$

1)$166,02+219,38=385,4$

2)$385,4:16,4=\frac{3854}{10} *\frac{10}{164} =\frac{3854}{164} =23,5$

3)$37,4*23,5=\frac{374}{10} *\frac{235}{10} =\frac{87890}{100}$

4)$73,2*48,3=\frac{732}{10} *\frac{483}{10} =\frac{353556}{100}$

5)$\frac{353556}{100}-\frac{87890}{100}=\frac{265666}{100} =2656,66$

№2

$227,36:(865,6-20,8*40,5)*8,38+1,12$

1)$20,8*40,5=\frac{208}{10} *\frac{405}{10} =\frac{84240}{100}$

2)$865,6-\frac{84240}{100}=\frac{8656}{10} -\frac{84240}{100}=\frac{86560}{100} -\frac{84240}{100}=\frac{2320}{100}$

3)$227,36:\frac{2320}{100}=\frac{22736}{100} *\frac{100}{2320} =\frac{22736}{2320} =9,8$

4)$9,8*8,38=\frac{98}{10} *\frac{838}{100} =\frac{82124}{1000} =\frac{8212,4}{100}$

5)$\frac{8212,4}{100}+1,12=\frac{8212,4}{100}+\frac{112}{100} =\frac{8324,4}{100} =83,244$

№3

$(7,061:2,3-2,2)*(4,2+17,391:5,27)$

1)$7,061:2,3=\frac{7061}{1000} :\frac{23}{10} =\frac{7061}{1000} *\frac{10}{23} =\frac{307}{100}$

2)$\frac{307}{100}-2,2=\frac{307}{100}-\frac{22}{10} =\frac{307}{100}-\frac{220}{100} =\frac{87}{100}$

3)$17,391:5,27=\frac{17391}{1000} :\frac{527}{100} =\frac{17391}{1000} *\frac{100}{527} =\frac{33}{10}$

4)$4,2+\frac{33}{10} =\frac{42}{10} +\frac{33}{10} =\frac{75}{10}$

5)$\frac{87}{100} *\frac{75}{10} =\frac{6525}{1000}=6,525$
