Question

решите пример : 1 2/23*2,07*2/9

Answer 1

$1 frac{2}{23} *2,07* frac{2}{9} = frac{25}{23} * frac{207}{100} *frac{2}{9}= \ \ \ =frac{25:25}{23} * frac{207:9}{100:25} *frac{2}{9:9}=frac{1}{23:23} * frac{23:23}{4} *frac{2}{3}= \ \ \ =frac{1}{1} * frac{1}{4:2} *frac{2:2}{3}=frac{1}{1} * frac{1}{2} *frac{1}{3}= frac{1*1*1}{1*2*3} = frac{1}{6}$
