Question

переведите дробь 1 5/8 в дес. прожалуйста

Answer 1

$1 frac{5}{8}=1+ frac{2*2.5}{2*4} =1+ frac{2.5}{4} =1+ frac{2*1.25}{2*2}=1+ frac{1.25}{2} =1+ frac{2*0.625}{2*1}=$
$=1+ frac{0.625}{1}=1+0.625=1.625$

$frac{15}{8}= frac{8*2-1}{8}= frac{8*2}{8*1}- frac{1}{8}= frac{2}{1}- frac{2*0.5}{2*4}=2- frac{0.5}{4}= 2- frac{2*0.25}{2*2}=$
$=2- frac{2*0.125}{2*1}=2- frac{0.125}{1}= 2-0.125=1.875$
