Question

[8-4,7:(5-0,8 : 8 supra 3 ) - 4 supra 5 * 1,25 ] : 0.1

Answer 1

[tex][8-4,7:(5-0,8 : \frac{8}{3} ) - \frac{4}{5} * 1,25 ] : 0.1=\ [/tex]
[tex][8-\frac{47}{10}:(5-\frac{8}{10}:\frac{8}{3})-\frac{4}5*\frac{125}{100}]:\frac{1}{10}= [/tex]
$[8-\frac{47}{10}:(5-\frac{8}{10}*\frac{3}{8})-\frac{4}5*\frac{125}{100}]*10=$
$[8-\frac{47}{10}:(5-\frac{24}{80})-\frac{500}{500}]*10=$
$[8-\frac{47}{10}:(\frac{400-24}{80})-1]*10=$
$(8-\frac{47}{10}:\frac{376}{80}-1)*10=$
$(8-\frac{47}{10}*\frac{80}{376}-1)*10=$
$(8-\frac{3760}{3760}-1)*10=$
$(8-1-1)*10=(8-2)*10=6*10=60$
