Question

1) - 6,3 * 10 2/3
2) 5,4 * ( - 1 1/9 )
3) - 5,2 : ( - 3 1/3 )
4) 63,21 : 5 1/4
5) 0,06 : 1,6 * 0,44 ( по действиям)

Answer 1

$1)-6.3*10 frac{2}{3} =-6 frac{3}{10} *10 frac{2}{3} =- frac{63}{10} * frac{32}{3} =- frac{63*32}{10*3} = \ =- frac{21*16}{1*5} =- frac{336}{5} =-67.2 \ 2)5.4*(-1 frac{1}{9} )=-(5 frac{4}{10} *1 frac{1}{9} )=-(5 frac{2}{5} *1 frac{1}{9} )=-( frac{27}{5} * frac{10}{9} )= \ =- frac{27*10}{5*9} =-3*2=-6 \ 3)-5.2:(-3 frac{1}{3} )=5 frac{2}{10} :3 frac{1}{3} = frac{52}{10} : frac{10}{3} = frac{52*3}{10*10} = frac{156}{100} =1.56$

$4)63.21:5 frac{1}{4} =63.21:5 frac{25}{100} = 63.21:5.25=12.04 \ 5)0.06:1.6*0.44=0.0165 \ 1)0.06:1.6= frac{6}{100} :1 frac{6} {10} = frac{3}{50} : frac{16}{10} = frac{3*10}{50*16} = frac{3}{5*16} = frac{3}{80} \ 2) frac{3}{80} *0.44= frac{3}{80} * frac{44}{100} = frac{3}{80} * frac{11}{25} = frac{33}{2000} =0.0165$
