Ответ
[tex]1) 1,68:0,8=\frac{1,68}{0,8}=\frac{168^{(8}}{80}=\frac{21}{10}=2,1[/tex]
[tex]2) 2,08:0,05=\frac{2,08}{0,05}=\frac{208^{(2}}{5}=\frac{416}{10}=41,6[/tex]
[tex]3) 86,1:0,41=\frac{86,1}{0,41}=\frac{8610^{(41}}{41}=\frac{210}{1} =210[/tex]
[tex]4) 1,64:0,41=\frac{1,64}{0,41}=\frac{164^{(41}}{41}=\frac{4}{1}=4[/tex]
[tex]5) 0,29:0,05 =\frac{0,29}{0,05}=\frac{29^{(2}}{5}=\frac{58}{10}=5,8[/tex]
[tex]6) 20,3:1,45=\frac{20,3}{1,45}=\frac{2030^{(5}}{145}= \frac{406^{(29}}{29} =\frac{14}{1}=14[/tex]
[tex]7) 60,75:0,9=\frac{60,75}{0,9}=\frac{6075^{(9}}{90}=\frac{675}{10}=67,5[/tex]
[tex]8) 0,016:0,08=\frac{0,016}{0,08}=\frac{16^{(8}}{80}=\frac{2}{10}=0,2[/tex]
[tex]9) 2,244:5,61=\frac{2,244}{5,61}=\frac{2244^{(2}}{5610}=\frac{1122^{(3}}{2805}=\frac{374^{(11}}{935} =\frac{34^{(17}}{85}= \frac{2^{(2}}{5} =\frac{4}{10}=0,4[/tex]
